Subject: [PATCH NEXT V2] rtlwifi: rtl8192c: rtl8192ce: Add support for B-CUT version of RTL8188CE

Realtek devices with designation RTL8188CE-VL have the so-called B-cut
of the wireless chip. This patch adds the special programming needed by
these devices.

V1 => V2 Remove extraneous white space.


John,

This patch is too invasive to backport to the stable kernels, thus it should
be applied to 3.7.

Thanks,

Larry
