gpu/drm: Ingenic: Fix opaque pointer casted to wrong type

2020-05-17T12:16:15+00:00

The opaque pointer passed to the IRQ handler is a pointer to the
drm_device, not a pointer to our ingenic_drm structure.

It still worked, because our ingenic_drm structure contains the
drm_device as its first field, so the pointer received had the same
value, but this was not semantically correct.

gpu/drm: ingenic: Fix bogus crtc_atomic_check callback

2020-05-17T12:14:17+00:00

The code was comparing the SoC's maximum height with the mode's width,
and vice-versa. D'oh.

drm/ingenic: Delete an error message in ingenic_drm_probe()

2020-04-07T18:48:41+00:00

The function “platform_get_irq” can log an error already.
Thus omit a redundant message for the exception handling in the
calling function.

This issue was detected by using the Coccinelle software.

drm/ingenic: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:04:18+00:00

Allows us to drop the drm_driver.release callback.

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)
