Subject: usb: dwc2: gadget: change variable name to more meaningful
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ba48eab8866ca71e7978380cf7564cf8240f28f8;p=linux-beck.git

usb: dwc2: gadget: change variable name to more meaningful

Since we handle FIFOs and endpoint separately, using variable named 'ep'
in context of FIFO is misleading, hence we rename it to 'fifo'.
