Subject: hwmon: (w83795) Fix parity checks
X-Git-Tag: upstream/snapshot3+hdmi~12601^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7eb8d508b5cfabbb147670ee063438469d94c465;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

hwmon: (w83795) Fix parity checks

x % 1 is obviously wrong, as it always evaluates to 0. You want
x % 2, or x & 1, for parity checking.
