3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Alex Deucher <[email protected]> commit 46783150a6552f9513f08e62cfcc07125d6e502b upstream. It seems it can corrupt the monitor EDID in certain cases on certain boards when running sensors detect. It's rarely used anyway outside of AIW boards. http://lists.lm-sensors.org/pipermail/lm-sensors/2012-April/035847.html http://lists.freedesktop.org/archives/xorg/2011-January/052239.html Signed-off-by: Alex Deucher <[email protected]> Acked-by: Jean Delvare <[email protected]> Signed-off-by: Dave Airlie <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/gpu/drm/radeon/radeon_i2c.c | 4 ++++ 1 file changed, 4 insertions(+) --- a/drivers/gpu/drm/radeon/radeon_i2c.c +++ b/drivers/gpu/drm/radeon/radeon_i2c.c @@ -890,6 +890,10 @@ struct radeon_i2c_chan *radeon_i2c_creat struct radeon_i2c_chan *i2c; int ret; + /* don't add the mm_i2c bus unless hw_i2c is enabled */ + if (rec->mm_i2c && (radeon_hw_i2c == 0)) + return NULL; + i2c = kzalloc(sizeof(struct radeon_i2c_chan), GFP_KERNEL); if (i2c == NULL) return NULL; -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
