Subject:
 [PATCH v1 04/23] drm/imagination: Discard pm_runtime_put() return value

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

The Imagination DRM driver defines pvr_power_put() to pass the return
value of pm_runtime_put() to the caller, but then it never uses the
return value of pvr_power_put().

Modify pvr_power_put() to discard the pm_runtime_put() return value and
change its return type to void.

No intentional functional impact.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

This patch is part of a series, but it doesn't depend on anything else
in that series.  The last patch in the series depends on it.

It can be applied by itself and if you decide to do so, please let me
know.

Otherwise, an ACK or equivalent will be appreciated, but also the lack
of specific criticism will be eventually regarded as consent.
