This patch fixes calling usleep_range() after taking reg_slock
using spin_lock_irqsave(). The mdelay() is used instead.
Waiting in atomic context is not the best idea in general.
Hopefully, waiting occurs only when Video Processor fails
to reset correctly.

Hello,
while looking through my local kernel tree, I noticed that this patch
for the mixer component of drm/exynos, posted some time ago, was
never applied. Since this is an obvious (and small) fix, could this
still go into 3.19?
With best wishes,
Tobias
