807a7515ae OMAP: DSS2: OMAPFB: fix crash when panel driver was not loaded
If the panel's probe had failed, omapfb would still go on, eventually
crashing.

A better fix would be to handle each display properly, and leaving just
the failed display out. But that is a bigger change.

66215949e6 omap1: Fix compile for omap1_bl.c
Commit 9905a43b made struct backlight_ops const. Omap was
setting check_fb dynamically, which caused the following
compile error:

drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe':
drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops'

Turns out pdata->check_fb is not being used, so just remove
it to fix the compile.

cfbd646fe0 intelfb: fix setting of active pipe with LVDS displays
The intelfb driver sets color map depending on currently active pipe.
However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set.  The default value is PIPE_A and can be wrong.  Set
up the pipe variable during driver initialization after hardware state was
read.

Also, the detection of the active display (and hence the pipe) is wrong.
The pipes are assigned to so called planes.  Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS).  Change active pipe detection code to take into
account a status of the plane assigned to each pipe.

The problem is visible in the 8 bpp mode if colors above 15 are used.  The
first 16 color entries are displayed correctly.

The graphics chip description is here (G45 vol. 3):

8097b1749f davinci: fb: calculate the clock divider from pixel clock info
The clock divider value can be calculated from the pixel clock value for
the panel.  This gives more flexiblity to the driver to change the divider
value on the fly as in the case of cpufreq feature- support for which will
be added shortly.

d2a34c13e7 drivers/video: Move dereference after NULL test
If the NULL test on fbi is needed, then the dereference should be after the
NULL test.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
  ... when != \(x = E\|&x\)
* x == NULL
// </smpl>

2f390380ca fbdev: add palette register check to several drivers
Add check if palette register number is in correct range for few drivers
which miss it.  The regno value comes indirectly from user space.

Two drivers has converted check from BUG_ON() macro to just return an
error (non-zero value).
