Subject: timer: print function name for timer callbacks modifying preemption count
From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
A function scheduled with a timer must not exit with a different preempt
count than it was entered. To make helping users running into the
corresponding BUG() easier also print the name of the bad function not
only its address.
