[PATCH 04/18] staging: rtl8188eu: simplify Hal_EfuseParseMACAddr_8188EU

[Martin Kaiser]

The hwinfo and AutoLoadFail parameters can be obtained from
struct adapter, there's no need to pass them as separate
function parameters.

Use memcpy instead of bytewise copy if we have to fall back to the
hard-coded mac address.
