Hi!

[ Upstream commit fd70e2019bfbcb0ed90c5e23839bf510ce6acf8f ]
Change logging from drm_{err,info}() to dev_{err,info}() in functions mtk_dp_aux_transfer() and mtk_dp_aux_do_transfer(): this will be essential to avoid getting NULL pointer kernel panics if any kind of error happens during AUX transfers happening before the bridge is attached.
This may potentially start happening in a later commit implementing aux-bus support, as AUX transfers will be triggered from the panel driver (for EDID) before the mtk-dp bridge gets attached, and it's done in preparation for the same.
This is preparation for patches we are not going to apply to stable. Please drop.
BR, Pavel
