Subject: imx:mx6 fix return value of mxc_get_clock
X-Git-Tag: v2015.01~91^2~20
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=eb412d79e476e871374ed1b8e561287746609018;p=oweals%2Fu-boot.git

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.
