Subject: drm: panel: orisetech: improve error handling during probe
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=640d512caa64b569e58a08b540d9c400e1aa8f94;p=users%2Fhch%2Fmisc.git

drm: panel: orisetech: improve error handling during probe

Use dev_err_probe() helper as directed by core driver model to handle
driver probe error. Use standard helper defined at drivers/base/core.c
to maintain code consistency.

Inspired by,
commit a787e5400a1ce ("driver core: add device probe log helper")
