return type of wait_for_completion_timeout is unsigned long not int, this patch uses the return value of wait_for_completion_timeout in the condition directly rather than adding a additional appropriately typed variable. Signed-off-by:

return type of wait_for_completion_timeout is unsigned long not int, this patch adds an appropriate variable and fixes up the assignment. It removes the else branch as the only thing it was doing is assigning ret = 0; - but ret is never used thereafter so that is not needed. As the string in dev_err already states "timeout" there is little point in printing the 0. A typo in "trasfer" -> transfer is also fixed. Signed-off-by:

Pull ARM SoC fixes from Olof Johansson: "One more week's worth of fixes. Worth pointing out here are: - A patch fixing detaching of iommu registrations when a device is removed -- earlier the ops pointer wasn't managed properly - Another set of Renesas boards get the same GIC setup fixup as others have in previous -rcs - Serial port aliases fixups for sunxi. We did the same to tegra but we caught that in time before the merge window due to more machines being affected.

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report on nested sleep conditions, which we generally want to avoid because the inner sleeping operation can re-set the thread state to TASK_RUNNING, but that will then cause the outer sleep loop not actually sleep when it calls schedule. However, that's actually valid traditional behavior, with the inner sleep being some fairly rare case (like taking a sleeping lock that normally doesn't actually need to sleep). And the debug code would actually change the state of the task to TASK_RUNNING internally, which makes that kind of traditional and working code not work at all, because now the nested sleep doesn't just sometimes cause the outer one to not block, but will cause it to happen every time. In particular, it will cause the cardbus kernel daemon (pccardd) to basically busy-loop doing scheduling, converting a laptop into a heater, as reported by Bruno Prémont. But there may be other legacy uses of that nested sleep model in other drivers that are also likely to never get converted to the new model. This fixes both cases: - don't set TASK_RUNNING when the nested condition happens (note: even if WARN_ONCE() only _warns_ once, the return value isn't whether the warning happened, but whether the condition for the warning was true. So despite the warning only happening once, the "if (WARN_ON(..))" would trigger for every nested sleep. - in the cases where we knowingly disable the warning by using "sched_annotate_sleep()", don't change the task state (that is used for all core scheduling decisions), instead use '->task_state_change' that is used for the debugging decision itself. (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the suggested change to use 'task_state_change' as part of the test) Reported-and-bisected-by:
