Subject: MIPS: ralink: mt7621: use bitwise NOT instead of logical
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5d8965704fe5662e2e4a7e4424a2cbe53e182670;p=linux.git

MIPS: ralink: mt7621: use bitwise NOT instead of logical

It was the intention to reverse the bits, not make them all zero by
using logical NOT operator.
