2011-02-02qeth: show new mac-address if its setting failsUrsula Braun
Setting of a MAC-address may fail because an already used MAC-address is to bet set or because of authorization problems. In those cases qeth issues a message, but the mentioned MAC-address is not the new MAC-address to be set, but the actual MAC-address. This patch chooses now the new MAC-address to be set for the error messages.

2011-02-02mac80211: fix TX status cookie in HW offload caseJohannes Berg
When the off-channel TX is done with remain-on-channel offloaded to hardware, the reported cookie is wrong as in that case we shouldn't use the SKB as the cookie but need to instead use the corresponding r-o-c cookie (XOR'ed with 2 to prevent API mismatches). Fix this by keeping track of the hw_roc_skb pointer just for the status processing and use the correct cookie to report in this case. We can't use the hw_roc_skb pointer itself because it is NULL'ed when the frame is transmitted to prevent it being used twice. This fixes a bug where the P2P state machine in the supplicant gets stuck because it never gets a correct result for its transmitted frame.

2011-02-02ASoC: fill in snd_soc_pcm_runtime.card before calling snd_soc_dai_link.init()Janusz Krzysztofik
The .card member of the snd_soc_pcm_runtime structure pointed to by the snd_soc_dai_link.init() argument used to be initialized before the function being called. This has changed, probably unintentionally, after recent refactorings. Since the function implementations are free to make use of this pointer, move its assignment back before the function is called to avoid NULL pointer dereferences.

2011-02-01OMAP3: Devkit8000: Change lcd power pinThomas Weber
This patch fixes a wrongly used lcd enable pin. The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.

2011-02-02mlock: operate on any regions with protection != PROT_NONEMichel Lespinasse
As Tao Ma noticed, change 5ecfda0 breaks blktrace. This is because blktrace mmaps a file with PROT_WRITE permissions but without PROT_READ, so my attempt to not unnecessarity break COW during mlock ended up causing mlock to fail with a permission problem. I am proposing to let mlock ignore vma protection in all cases except PROT_NONE. In particular, mlock should not fail for PROT_WRITE regions (as in the blktrace case, which broke at 5ecfda0) or for PROT_EXEC regions (which seem to me like they were always broken).
