The patch "module: fix types of device tables aliases" newly requires that
invocations of

MODULE_DEVICE_TABLE(type, name);

come *after* the definition of `name'.  That is reasonable, but some
drivers weren't doing this.  Fix them.

After waking up a task waiting for an event, we explicitly mark it as
TASK_RUNNING (which is necessary as we do the checks for wakeups as
TASK_INTERRUPTIBLE).  Once running and dealing with actually delivering
the events, we're obviously not planning on calling schedule, thus we can
relax the implied barrier and simply update the state with
__set_current_state().

bsd and sysv use different typedefs for unsigned types.

These are in types.h but not in checkpatch, so add them to checkpatch's
ability to know types.

This can avoid false positives for code like:

void foo(void)
{
	int x;
	uint y;

	[...];
}

where checkpatch incorrectly emits a warning for "missing a blank line
after declarations".
