Subject: drm/mediatek: mtk_dpi: remove invalid error message
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=515ba6a59cbab44c989f25b2518b82491deb832e;p=linux-beck.git

drm/mediatek: mtk_dpi: remove invalid error message

Do not try to dereference dpi if it is NULL.
Since dpi can never be NULL when mtk_dpi_set_display_mode() is called,
remove the message.
