[PATCH drm/hisilicon v2 2/3] drm/hisilicon: Code refactoring for hibmc_drv_de

[Tian Tao]

The memory used to be allocated with devres helpers and released
automatically. In rare circumstances, the memory's release could
have happened before the DRM device got released, which would have
caused memory corruption of some kind. Now we're embedding the data
structures in struct hibmc_drm_private. The whole release problem
has been resolved, because struct hibmc_drm_private is allocated
with drmm_kzalloc and always released with the DRM device.

v2:
edit commit message.

Sorry for all my reviews taking so long. Please merge patch #3 into
patch #2 and then the series is

Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de>

I noticed that hibmc use DRM_ERROR in several places. A good follow-up
patchset would be the conversion to drm_info/drm_warn/drm_error/etc.

Best regards
