With applications like MythTV, switching inputs results in closing the digital side and then immediately opening the analog side. This exposes a race condition where the dvb_frontend kernel thread powers down the chip and closes the i2c gate even though we're in the middle of bringing up the analog part of the chip (since the shutdown of the dvb_frontend kernel thread occurs asychronously). Introduce a construct to keep track of what mode we're in, and drop requests to power down or management the gate if we've already switched to analog mode. Thanks to Zaphod Beeblebrox for reporting this issue. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
