From: Andy Shevchenko Date: Wed, 21 Apr 2021 16:31:57 +0000 (+0300) Subject: drm/hx8357d: Avoid spamming logs if probe is deferred X-Git-Tag: accepted/tizen/unified/20230118.172025~6402^2~28^2~528 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=749da85a9a527c78f35cfa3f918a57644eb12908;p=platform%2Fkernel%2Flinux-rpi.git drm/hx8357d: Avoid spamming logs if probe is deferred 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().
