[3/6] staging: wilc1000: host_interface.c : removes unused local variables

Commit Message

Tony Cho Oct. 5, 2015, 10:28 a.m. UTC

From: Leo Kim <[e-mail]>

This patch removes unused local variables from host_interface.c.
The unused local variable, s32Error is used just to return zero, so this
patch calls "returns 0" instead of "return s32Error" after removing
s32Error.
