Subject: [media] az6007: Comment the gate_ctl mutex
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2212501ffad7fee1c2fcf9d6d55a24b489da18ad;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[media] az6007: Comment the gate_ctl mutex

The mutex is there to protect the I2C gate. However, for some reason,
it is being called twice:

[ 2103.542796] usbcore: registered new interface driver dvb_usb_az6007
[ 2103.772392] az6007: drxk_gate_ctrl: enable
[ 2103.793900] az6007: drxk_gate_ctrl: enable

For now, let's just comment, to allow the driver to run.
