This series corrects incorrect calls to request_irq(..., IRQF_ONESHOT, ...). These anomalies are harmless on regular kernels but cause odd behaviour on threadirq kernels and break entirely on PREEMPT_RT kernels
I'm pretty certain these problems would also provoke lockdep splats on kernels with CONFIG_PROVE_RAW_LOCK_NESTING enabled (because that is intended to find code that breaks entirely on PREEMPT_RT kernels ;-) ).
Finally, and just in case anybody asks, yes! I did use coccinelle to do a quick scan for similar issues. I didn't find any other instances in drivers/drm/ .
