Again, this needs a proper changelog.  It also needs style fixes:

WARNING: sizeof buf should be sizeof(buf)
#16: FILE: drivers/gpu/drm/i2c/tda998x_drv.c:338:
+	ret = i2c_master_send(client, buf, sizeof buf);

WARNING: sizeof buf should be sizeof(buf)
#35: FILE: drivers/gpu/drm/i2c/tda998x_drv.c:453:
+	ret = i2c_master_send(client, buf, sizeof buf);

WARNING: sizeof buf should be sizeof(buf)
#44: FILE: drivers/gpu/drm/i2c/tda998x_drv.c:469:
+	ret = i2c_master_send(client, buf, sizeof buf);

total: 0 errors, 3 warnings, 49 lines checked

Your patch has style problems, please review.

Hence, it has only been tested.  I'm not giving an acked-by until the
above issues are addressed.

Tested-by: Russell King <rmk+kernel@arm.linux.org.uk>
