Merge branch 'drm-tda998x-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull TDA998x i2c driver fixes from Russell King: "This fixes the double-checksumming of the AVI infoframe which was resulting in the checksum always being zero. It went unnoticed as none of my HDMI devices had a problem with this" [ Pulling directly from rmk since Dave Airlie is on vacation - Linus ] * 'drm-tda998x-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: drm/i2c: tda998x: fix bad checksum of the HDMI AVI infoframe
