[PATCH] bttv: fix dst i2c read/write timeout failure.
Attached is a patch to bttv which fixes the following problems. Affected cards and problems: ~~~~~~~~~~~~~~~~~~~~~~~~ o VP-1020 (200103A) Tuning problems, device detection. o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while. o VP-1030 (DST-CI) Tuning sometimes fails after CI commands. o VP-2031 (DCT-CI) Tuning problems The timeout happens before the actual timeout occured in the MCU on the board, and hence the problems. Changes: (bttv-i2c.diff) ~~~~~~~~~~~~~~~~~~~~~~~~ o Changed the custom wait queue to wait_event_interruptible_timeout() - Suggestion by Johannes Stezenbach. o Fixed the wait queue timeout problem - This fixes the timeout problem on various cards. - This problem was visible as many * Cannot tune to channels, when signal levels are very low. * app_info does not work in some conditions for CI based cards - Smaller values worked good for newer cards, but the older cards suffered, settled down to the worst case values that could happen in any eventuality.
