Subject: [patch] usb: dwc3: gadget: fix mask and shift order in DWC3_DCFG_NUMP()
Date: Tue, 3 May 2016 10:49:00 +0300 [thread overview]
Message-ID: <20160503074900.GA9816@mwanda> (raw)
In the original DWC3_DCFG_NUMP() was always zero. It looks like the
intent was to shift first and then do the mask.
Fixes: 2a58f9c12bb3 ('usb: dwc3: gadget: disable automatic calculation of ACK TP NUMP')
