X-Git-Tag: cont_sys_log_2~10^2~1 X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=d294ed69408b54c18f0420516ea057b2a734624d drm/radeon: reset i2c valid to avoid incorrect tv-out polling. We really don't want to be polling tv-out but since we weren't forcing the i2c lines to invalid (tv-out has no DDC), we were adding tv connectors to the polling setup and this was causing blinking on secondary displays. This fixes the regression Torsten reported.
