Subject: [PATCH] hwspinlock: qcom: Correct msb in regmap_field

From: Bjorn Andersson <bjorn.andersson@...ymobile.com>

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.
