Subject: usb: gadget: f_uac2: add short-hand for 'dev'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a8147dabe56f7e7a4975e60abb613f7e62277577;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

usb: gadget: f_uac2: add short-hand for 'dev'

In afunc_bind() and afunc_set_alt(), &uac2->pdev.dev are used multiple
times. Adding a short-hand for them makes lines shorter so we can
remove some line wraps.

No functional change.
