Subject: crypto: mediatek - remove redundant bitwise-or
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a52485165d85b008d8ebb03884350b11039580e1;p=linux.git

crypto: mediatek - remove redundant bitwise-or

Bitwise-or'ing 0xffffffff with the u32 variable ctr is the same result
as assigning the value to ctr.  Remove the redundant bitwise-or and
just use an assignment.

Addresses-Coverity: ("Suspicious &= or |= constant expression")
