From 1a8b294ce6b0cdab438175eed45ebb088bdd659a Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Mon, 18 Jun 2012 17:08:08 +0200 Subject: [PATCH] HID: uhid: silence gcc warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gcc is giving me: drivers/hid/uhid.c: In function ‘uhid_hid_get_raw’: drivers/hid/uhid.c:157: warning: ‘len’ may be used uninitialized in this function which is clearly bogus, as - when used as memcpy() argument, it's initialized properly - the code is structured in a way that either 'ret' or 'len' is always initialized, so the return statement always has an initialized value.
