| Subject: [PATCH] i915: bogus warning from i915 when running on PREEMPT_RT |
| |
| 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 |
