From eb412d79e476e871374ed1b8e561287746609018 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Sun, 23 Nov 2014 11:52:20 +0800 Subject: [PATCH] imx:mx6 fix return value of mxc_get_clock mxc_get_clock's return type is unsigned int. 'return -1' is same with 'return 0xffffffff', so 0 should be used as the return value when unsupported mxc_clock type is passed to mxc_get_clock. Also include an err message when unsupported mxc_clock type is passed to mxc_get_clock.
