Subject: [PATCH 0/2] Balance mutex_init and mutex_destroy calls
Date: Mon,  7 Nov 2022 19:46:54 -0300	[thread overview]
Message-ID: <20221107224656.278135-1-mcanal@igalia.com> (raw)

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
