Subject: [PATCH 3/4] drm/msm/adreno: drop redundant pm_runtime_disable()
Date:   Tue, 21 Feb 2023 11:14:29 +0100
Message-Id: <20230221101430.14546-4-johan+linaro@kernel.org>

Since commit 4b18299b3365 ("drm/msm/adreno: Defer enabling runpm until
hw_init()") runtime PM is no longer enabled at adreno_gpu_init(), which
means that there are no longer any bind() error paths for which
adreno_gpu_cleanup() is called with runtime PM enabled.

As the runtime PM enable on first open() is balanced by the
pm_runtime_force_suspend() call at unbind(), adreno_gpu_cleanup() is now
always called with runtime PM disabled so that its pm_runtime_disable()
call can be removed.
