Subject: drm/mipi_dbi: Use drmm_add_final_kfree in all drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: f5ad671b2963d335e4eda195291c68a0409808d6
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
They all share mipi_dbi_release so we need to switch them all
together. With this we can drop the final kfree from the release
function.
Aside, I think we could perhaps have a tiny additional helper for
these mipi_dbi drivers, the first few lines around devm_drm_dev_init
are all the same (except for the drm_driver pointer).
