Hello all, Here's the scenario: 1. I have a USB device that supports both an analog tuner and composite/s-video inputs 2. The bridge is smart enough to power down the tuner when capturing on composite/s-video 3. Changing the video standard appears to send set_freq() calls to the tuner, which in i2c fail because it's powered down. So I looked at the tuner-core code, and I'm seeing that tuner_s_std() will call set_freq() if the tuner->tv_freq field is nonzero. This seems reasonable, except as far as I can tell there is no way to set it to zero (because the places that set the value to zero will return failure because zero is outside the tuning range). This behavior happens with tvtime, which always does a tuning on startup, before switching to the A/V inputs. While I agree that I should probably fix tvtime so it doesn't do this, it seems strange that there is no way to reset tv_freq to zero when toggling away from the tuner input, so that these errors don't occur. Any thoughts? Obviously I would like to eliminate the i2c errors from littering the dmesg log when there is no real failure condition. Devin -- Devin J.
