Colin Ian King e52398d49d drm/mediatek: avoid dereferencing a null hdmi_phy on an error message ... [ Upstream commit b097efba9580d1f7cbc80cda84e768983e3de541 ] Currently there is a null pointer check for hdmi_phy that implies it may be null, however a dev_err messages dereferences this potential null pointer. Avoid a null pointer dereference by only emitting the dev_err message if hdmi_phy is non-null. It is a moot point if the error message needs to be printed at all, but since this is a relatively new piece of code it may be useful to keep the message in for the moment in case there are unforseen errors that need to be reported.
