drm/ili9486: Use devm_drm_dev_alloc

2020-04-28T13:48:07+00:00

Already using devm_drm_dev_init, so very simple replacment.

drm/mipi-dbi: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:09:10+00:00

Allows us to drop the drm_driver.release callback from all
drivers, and remove the mipi_dbi_release() function.

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

drm/mipi-dbi: Move drm_mode_config_init into mipi library

2020-03-26T15:09:03+00:00

7/7 drivers agree that's the right choice, let's do this.

This avoids duplicating the same old error checking code over all 7
drivers, which is the motivation here.

drm/mipi_dbi: Use drmm_add_final_kfree in all drivers

2020-03-26T13:49:51+00:00

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).
