Subject: drm: Use IS_ERR() instead of IS_ERR_OR_NULL()
Git-commit: 39b14bb5915f5c68585161339d75d2f47d2a7e20
Patch-mainline: v5.16-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
dev_pm_opp_find_freq_exact never return null but ERR_PTR(),so we
should use IS_ERR() to clarify and avoid compilation warnings.
