From 8dca51071849077e83ec85b7e5d46c84cee227d9 Mon Sep 17 00:00:00 2001 From: Bin Liu Date: Mon, 21 May 2018 08:42:21 -0500 Subject: [PATCH] usb: musb: gadget: fix to_musb_request() to not return NULL The gadget function drivers should ensure the usb_request parameter passed in is not NULL. UDC core doesn't check if it is NULL, so MUSB driver shouldn't have to check it either. Convert to_musb_request() to a simple macro to not directly return NULL to avoid warnings from code static analysis tools.
