Subject: i915: bogus warning from i915 when running on PREEMPT_RT
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.4-rc6-rt1/patches-4.4-rc6-rt1.tar.xz
|
|
|
|
The i915 driver has a 'WARN_ON(!in_interrupt())' in the display
|
|
handler, which whines constanly on the RT kernel (since the interrupt
|
|
is actually handled in a threaded handler and not actual interrupt
|
|
context).
|
|
|
|
Change the WARN_ON to WARN_ON_NORT
