[PATCH] staging: rtl8192u: remove redundant null check on array alg

From: Colin King
Date: Thu Feb 09 2017 - 06:58:47 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

u.crypt.alg is an array of u8 integers and hence the null check on
this array is redundant and can be removed.

Detected with CoverityScan, CID#143214 ("Array compared against 0")
