Subject: staging: wilc1000: Remove unnecessary array index check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1cbe5fe261a19b4a9a482cd24b12d1d063abaa44;p=linux.git

staging: wilc1000: Remove unnecessary array index check

This statment triggers GCC's -Wtype-limit since key_index is an
unsigned integer so it cannot be less than zero.
