X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93ce675c5cc57cac37e32953fdd43179e02f5c54;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[media] mxl111sf-tuner: use DVBv5 parameters on set_params()

Instead of using DVBv3 parameters, rely on DVBv5 parameters to
set the tuner
