Subject: net/nuc900: enable Mac driver clock
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d1853dc8fa8e6478707bf5d8e9d0b949974c2dde;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

net/nuc900: enable Mac driver clock

This patch fixed a bug that Mac driver does not work,because I missed the clk enable.

I have ever tested the driver when I submitted previous Mac driver patch,
and it worked good, since my bootloader has enabled the clock in advance.

But when I try to use other bootloader where clock engine was disabled,the
Mac driver does not work, so I send this patch to fix this issue.
