Subject: [PATCH] usb: dwc2: gadget: Fix fifo size configuration
Date: Mon, 19 Dec 2016 15:42:45 +0000 [thread overview]
Message-ID: <1482162166-6845-1-git-send-email-stefan.wahren@i2se.com> (raw)
Currently the upper limit for the endpoint index during fifo size
config was always 16 instead of the available endpoints. So fix this
by using the determined amount of endpoints and avoid a warning about
"insufficient fifo memory" on bcm2835 which has only 8 endpoints.
