drm/i2c: tda998x: fix bad checksum of the HDMI AVI infoframe
The commit 8c7a075d "drm/i2c: tda998x: use drm_hdmi_avi_infoframe_from_display_mode()" also uses hdmi_avi_infoframe_pack() to create the AVI infoframe. This function sets the checksum of the frame and this breaks the second calculation of the checksum done in tda998x_write_if(). Fixes: 8c7a075d ("drm/i2c: tda998x: use drm_hdmi_avi_infoframe_from_display_mode()") Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
