From e945953dd736b5f385fbb4b7ab368271dff5714a Mon Sep 17 00:00:00 2001 From: Bin Liu Date: Wed, 1 Feb 2017 21:30:13 -0600 Subject: [PATCH] usb: musb: remove musb_generic_disable function musb_generic_disable() only has two lines of code. So remove it and let the callers directly call those two lines.
