[PATCH] em28xx: make sure that all subdevices are powered on when needed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit 622b828ab7 ("v4l2_subdev: rename tuner s_standby operation to
core s_power") replaced the tuner s_standby call in the em28xx driver with
a (s_power, 0) call which suspends all subdevices.
But it neglected to add corresponding (s_power, 1) calls to make sure that
the subdevices are powered on again when needed.

This patch fixes this issue by adding a (s_power, 1) call to
function em28xx_wake_i2c().
