Subject: drm/imx: plane_state->fb iff plane_state->crtc
Git-commit: 4efb31316d5f317cc83cbc4a983327311ae959e6
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Checking both is one too much, so wrap a WARN_ON around it to stope
the copypasta.
