Subject: gpio: wcove: Allow return negative error code from to_reg()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=282db906eecccb08b8f0adccd082a129ae1d95d8;p=openwrt%2Fstaging%2Fblogic.git

gpio: wcove: Allow return negative error code from to_reg()

The type of to_reg() is unsigned int while it might return
a negative error code. Callers are also expecting a signed type.

For sake of type consistency replace unsigned int with plain int.
