From 3565b787fdf0ed52c94072b8f363a3b15b52d646 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 16 Jun 2017 10:40:58 -0500 Subject: [PATCH] usb: musb: tusb6010_omap: Use one musb_ep_select call in tusb_omap_dma_program Having one musb_ep_select() instead the two calls in if/else is the same thing, but makes the code a bit simpler to follow.
