Subject: [PATCH 00/14] drm/panel: Use refcounted allocation in place of
 devm_kzalloc() - Part5

Use the new API devm_drm_panel_alloc() for panel allocations.
A major chunk of driver conversion was sent in a 3 part series
which is already merged. The coccinelle patch that was used to
identify unsafe panel allocations didnt flag about 20 drivers.

Not using any semantic patch for the remaining drivers.
This series does the conversion by not passing explicit type
to the helper and maintaining type safety suggested by Geert.

Link to part 1, 2 and 3 of driver conversion:
https://patchwork.freedesktop.org/series/147082/
https://patchwork.freedesktop.org/series/147157/
https://patchwork.freedesktop.org/series/147246/

Link to part 4 that incorporates type safety:
https://patchwork.freedesktop.org/series/151355/

Geert's suggestion
https://lore.kernel.org/dri-devel/CAN9Xe3TXZa1nrCLkHadiBkOO=q1ue8Jwc3V13pXcbAc9AFS2-Q@mail.gmail.com/

This is the final set of drivers.

A total of 86 drivers covered in part 1, 2 and 3 are converted
by passing explicit type and is not type safe. Changes to those
will be addressed in the upcoming series.
