[PATCH v2 0/2] Balance mutex_init and mutex_destroy calls

[Maíra Canal]

This series introduces some changes to assure the correct resource release on
the V3D driver, especially the mutex. Currently, the V3D has no mutex_destroy()
calls, which means that a mutex is being instantiated, but it is not being
released by the end of its use.

So, use the DRM-managed mutex_init variants when possible to manage the mutex
release and add mutex_destroy() calls when not possible.

Best Regards,
- Maíra Canal

v1 -> v2: https://lore.kernel.org/dri-devel/20221107224656.278135-1-mcanal@xxxxxxxxxx/T/#m3c23e3f21fe6aaae51138c746c74e94b2a7b3bfc

- Move mutex_destroy() to v3d_perfmon_put() (Daniel Vetter).
- Add mutex_destroy() on error case in v3d_perfmon_create_ioctl() (Daniel Vetter).
- Add Daniel Vetter's tags.

  drm/v3d: switch to drmm_mutex_init
  drm/v3d: add missing mutex_destroy
