Subject: usb: gadget: apply generic altsetting support check mechanism
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=736d093b5985c1f6583460c8eea1be3c9ee5635e;p=linux-beck.git

usb: gadget: apply generic altsetting support check mechanism

Replace calls of gadget_supports_altsettings() function (which check altset
support by comparing UDC controller name with hardcoded names) with
gadget_is_altset_supported() which checks generic quirk bitfield.
