Daniel Mack 5d6b1edf8c [ARM] pxamci: call mmc_remove_host() before freeing resources ... mmc_remove_host() will cause the mmc core to switch off the bus power by eventually calling pxamci_set_ios(). This function uses the regulator or the GPIO which have been freed already. This causes the following Oops on module unload.
