[PATCH 1/2] staging: ks7010: Unnecessary parentheses are removed to make coder nicer.

[PATCH 1/2] staging: ks7010: Unnecessary parentheses are removed to make coder nicer.

[Arushi Singhal]

Unnecessary parentheses should be avoided as reported by checkpatch.pl.
Remove unnecessary parentheses, as reported by checkpatch as are nicer
to read.For example:-
It's often nicer to read if &(foo[0]) is converted to foo like:
     memcpy(&(ap->bssid[0]), &(ap_info->bssid[0]), ETH_ALEN);
     memcpy(ap->bssid, ap_info->bssid, ETH_ALEN);
