Subject: [PATCH] usb: gadget: dwc2_udc_otg: set ep's desc during enable/disable
Date: Thu, 6 Jan 2022 16:02:08 +0100 [thread overview]
Message-ID: <20220106150208.1316946-1-gary.bisson@boundarydevices.com> (raw)
Fastboot support has been broken on platforms using dwc2 controller
since the gadget gets its max packet size from it.
This patch is the equivalent of 723fd5668ff which fixed the same issue
but for the chipidea controller.
Fixes: 27c9141b111 ("usb: gadget: fastboot: use correct max packet size")
