Subject: hwspinlock: qcom: Correct msb in regmap_field
X-Git-Tag: v4.14-rc1~5092^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bd5717a4632cdecafe82d03de7dcb3b1876e2828;p=platform%2Fkernel%2Flinux-rpi.git

hwspinlock: qcom: Correct msb in regmap_field

msb of the regmap_field was mistakenly given the value 32, to set all bits
in the regmap update mask; although incorrect this worked until 921cc294,
where the mask calculation was corrected.
