V4L/DVB: ivtv: Combine capture start delays into a single delay
Browse files Browse the repository at this point in the history
Combine the two 150 ms delays into a single 300 ms delay.  Ian Armstrong has
noted that the delay between CX2341X_ENC_INITIALIZE_INPUT and
CX2341X_ENC_START_CAPTURE can cause problems if the temporal filter is allowed
to be enabled.
