[PATCH v2 0/2] drm/msm: Remove spurious IRQF_ONESHOT flags from dsi & hdmi

[Daniel Thompson]

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/ .

Changes in v2:
 - Split into separate patches (Dmitry B)

Daniel Thompson (2):
  drm/msm/dsi: Remove spurious IRQF_ONESHOT flag
  drm/msm/hdmi: Remove spurious IRQF_ONESHOT flag
