Subject: usb: gadget: net2280: use ep_autoconfig compatible names in advance mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a285f40d80d440853ac908017d6d949ae2a7f88e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

usb: gadget: net2280: use ep_autoconfig compatible names in advance mode

Each struct usb_ep added for net2280 can be used in either direction.
Whereas, each struct usb_ep for usb3380 has fixed direction. Use
ep_autoconf compatible names so that endpoint with correct direction
can be selected.

Name sequence is due to the logic in usb_reinit_338x() in ne[] and
ep_reg_addr[].
