From 21f3bb52986c5f0ab74d350486de38fafff6ddef Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Mon, 29 Aug 2016 13:38:57 -0700 Subject: [PATCH] usb: dwc2: gadget: remove dead code from dwc2_hsotg_ep_enable() Since FIFO is always freed in dwc2_hsotg_ep_disable(), ep->fifo_index is always 0 in dwc2_hsotg_ep_enable(), hence code inside if() block is never executed.
