981cbef2c3 V4L/DVB: video: testing unsigned for less than 0
soc_mbus_bytes_per_line() returns -EINVAL on error but we store it in an

03b1930efd V4L/DVB: saa7146: fix regression of the av7110/budget-av driver
An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.

As part of upstream merge, set_params() function was removed from isif.c.
This requires removal of BUG_ON() and check for set_params ptr in
vpfe_capture.c. Without this kernel crash dump is seen while bootup on DM365

Also made following changes:-

 1) converted error messages to debug messages since it is not right to flood
    the console with error messages for user mistakes.
 2) returns -EINVAL if ioctl is not supported

11439a6fd9 PNP: don't check for conflicts with bridge windows
With fa35b4926, I broke a lot of PNP resource assignment.  That commit made
PNPACPI include bridge windows as PNP resources, and PNP resource assignment
treats any enabled overlapping PNP resources as conflicts.  Since PCI host
bridge windows typically include most of the I/O port space, this makes PNP
port assigments fail.

The PCI host bridge driver will eventually use those PNP window resources,
so we should make PNP ignore them when checking for conflicts.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=15903

07bedca29b ACPI: DMI init_set_sci_en_on_resume for multiple Lenovo ThinkPads
Multiple Lenovo ThinkPad models with Intel Core i5/i7 CPUs can
successfully suspend/resume once, and then hang on the second s/r
cycle.

We got confirmation that this was due to a BIOS defect. The BIOS
did not properly set SCI_EN coming out of S3. The BIOS guys
hinted that The Other Leading OS ignores the fact that hardware
owns the bit and sets it manually.

In any case, an existing DMI table exists for machines where this
defect is a known problem. Lenovo promise to fix their BIOS, but
for folks who either won't or can't upgrade their BIOS, allow
Linux to workaround the issue.

https://bugzilla.kernel.org/show_bug.cgi?id=15407
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/532374

Confirmed by numerous testers in the launchpad bug that using
acpi_sleep=sci_force_enable fixes the issue. We add the machines
to acpisleep_dmi_table[] to automatically enable this workaround.

b1d4b390ea i2c: Fix probing of FSC hardware monitoring chips
Some FSC hardware monitoring chips (Syleus at least) doesn't like
quick writes we typically use to probe for I2C chips. Use a regular
byte read instead for the address they live at (0x73). These are the
only known chips living at this address on PC systems.

For clarity, this fix should not be needed for kernels 2.6.30 and
later, as we started instantiating the hwmon devices explicitly based
on DMI data. Still, this fix is valuable in the following two cases:
* Support for recent FSC chips on older kernels. The DMI-based device
  instantiation is more difficult to backport than the device support
  itself.
* Case where the DMI-based device instantiation fails, whatever the
  reason. We fall back to probing in that case, so it should work.

This fixes kernel bug #15634:

e4a7b9b04d i2c-core: Erase pointer to clientdata on removal
After discovering that a lot of i2c-drivers leave the pointer to their
clientdata dangling, it was decided to let the core handle this issue.
It is assumed that the core may access the private data after remove()
as there are no guarantees for the lifetime of such pointers anyhow (see
thread starting at http://lkml.org/lkml/2010/3/21/68)

e938fbfd4a Input: elantech - ignore high bits in the position coordinates
In older versions of the elantech hardware/firmware those bits always
were unset, so it didn't actually matter, but newer versions seem to
use those high bits for something else, screwing up the coordinates
we report to the input layer for those devices.

Apparently hardware vendors now ship elantech touchpads with different version
magic. This options allows for them to be tested easier with the current driver
in order to add their magic to the whitelist later.

5132088697 Input: ati_remote - add some missing devices from lirc_atiusb
The (out-of-tree) lirc_atiusb driver has a much longer list of devices
it supports.  Some of them look like they may just be guesses at possible
device IDs, but a few are definitely confirmed devices.  This adds the
nVidia-branded RF receiver and the X10 Lola Wireless Video Sender device
(which contains an RF receiver) to the list of devices in ati_remote.

1827d2e943 net: ep93xx_eth stops receiving packets
Receiving small packet(s) in a fast pace leads to not receiving any
packets at all after some time.

After ethernet packet(s) arrived the receive descriptor is incremented
by the number of frames processed. If another packet arrives while
processing, this is processed in another call of ep93xx_rx. This
second call leads that too many receive descriptors getting released.

This fix increments, even in these case, the right number of processed
receive descriptors.

e9162ab161 dm9601: fix phy/eeprom write routine
Use correct bit positions in DM_SHARED_CTRL register for writes.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which
came with a driver CD containing a Linux driver. This driver turns out to
be a copy of dm9601.c with symbols renamed and my copyright stripped.
That aside, it did contain 1 functional change in dm_write_shared_word(),
and after checking the datasheet the original value was indeed wrong
(read versus write bits).

On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s.
On other devices the difference is less spectacular, but still significant
(~30%).

19937d0482 ppp_generic: handle non-linear skbs when passing them to pppd
Frequently when using PPPoE with an interface MTU greater than 1500,
the skb is likely to be non-linear. If the skb needs to be passed to
pppd then the skb data must be read correctly.

The previous commit fixes an issue with accidentally sending skbs
to pppd based on an invalid read of the protocol type. When that
error occurred pppd was reading invalid skb data too.

ea8420e9f5 ppp_generic: pull 2 bytes so that PPP_PROTO(skb) is valid
In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb.

If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then
the packet is passed directly to pppd.

This occurs frequently when using PPPoE with an interface MTU
greater than 1500 because the skb is more likely to be non-linear.

The next 2 bytes need to be pulled in ppp_input(). The pull of 2
bytes in ppp_receive_frame() has been removed as it is no longer
required.
