[PATCH v3 07/24] drm/i2c: tda998x: set the video mode from the adjusted value
From: Jean-Francois Moine <hidden>
Date: 2014-01-19 19:00:51
This patch uses always the adjusted video mode instead of a mix of original and adjusted mode. Signed-off-by: Jean-Francois Moine <redacted> --- drivers/gpu/drm/i2c/tda998x_drv.c | 66 +++++++++++++++++++-------------------- 1 file changed, 33 insertions(+), 33 deletions(-)
