[PATCH 0/2] Balance mutex_init and mutex_destroy calls

Posted by Maíra Canal 3 years, 5 months ago

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

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