From fb91cddc54e71a09b31e0fdf2d45abeaea850113 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 1 May 2015 12:29:30 -0700 Subject: [PATCH] usb: musb: Remove DMA ifdef for musb_gadget.c short_packet Let's get rid of the horrible ifdef in middle of the expression. We can do it by adding a variable for short_packet and testing it separately for DMA related code.
