From d871c622e202efc663f953a4fcbd2cba6a28a24f Mon Sep 17 00:00:00 2001 From: George Cherian Date: Wed, 16 Jul 2014 18:22:11 +0530 Subject: usb: musb: core: Convert the musb_platform_reset to have a return value. Currently musb_platform_reset() is only used by dsps. In case of BABBLE interrupt for other platforms the musb_platform_reset() is a NOP. In such situations no need to re-initialize the endpoints. Also in the latest silicon revision of AM335x, we do have a babble recovery mechanism without resetting the IP block. In preperation to add that support its better to have a rest_done return for musb_platform_reset().
