[PATCH v1 7/7] drm/hx8357d: Avoid spamming logs if probe is deferred

From: Andy Shevchenko
Date: Wed Apr 21 2021 - 12:32:07 EST


The GPIO request can fail and probe may be deferred. Thus,
the error message may be printed again and again. Avoid
this by replacing DRM_DEV_ERROR() by dev_err_probe().
