Subject: drm/panfrost: devfreq: Don't display error for EPROBE_DEFER
Git-commit: 8626e63eeea8fac24849c652c35c61e56f01b09b
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Set a condition for the message of "Couldn't set OPP regulators" to not
display if the error code is EPROBE_DEFER. Note that I used an if
statement to capture the condition instead of the dev_err_probe
function because I didn't want to change the DRM_DEV_ERROR usage.
