V4L/DVB (9069): cx88: Bugfix: all client disconnects put the frontend to sleep. (3e010845) · Commits · e / devices / android_kernel_teracube_2e

From the author: "This fixes the problem where previously all client disconnects put the analogue frontend into standby. In the following example, the first command is succesfully watching TV but the second command which returns EBUSY detunes the receiver by entering it into the standby state. tvtime -d /dev/video0 & cat /dev/video0 " Signed-off-by:
