Subject: [media] dvb_usb_v2: restore .firmware - pointer to name
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=005bc3fce76b3bd7c0a583cf3e89ce11c87077cd;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[media] dvb_usb_v2: restore .firmware - pointer to name

Most commonly only one firmware is used by the driver
and it is not needed to selected run time. So restore
old functionality but allow .get_firmware_name() callback
to override it.
