Store the (struct rc_dev *) "dev" input argument on the stack

Move (struct rc_dev *) dev into %eax

&dev->rc_map->lock

But that's where the Oops always happens, so the "dev" input argument to
the function is NULL.

Someone familiar with the driver/media/rc/imon.c file needs to figure
out how rc_g_keycode_from_table() can be called with a NULL first
argument: ictx->rdev is NULL when
rc_g_keycode_from_table(ictx->rdev,...) is called.

There might be some race at driver initialization, given that at first
look ictx-rdev being NULL seems impossible.  Your stack backtraces
always indicate some sort of IRQ context, so maybe that matters.

Andy
