Subject: Input: wm831x-ts - remove use of ternary operator
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=723d928417bffff6467da155d8ebbbe016464012;p=openwrt%2Fstaging%2Fblogic.git

Input: wm831x-ts - remove use of ternary operator

While being applied the driver was modified to add use of the ternary
operator. Write the conditionals out longhand as I find it terribly
unhelpful for legibility.
