Subject: Input: ati_remote2 - return the error code from sysfs channel_mask store
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7388754e0399d341e6d02fc7394b3727cad57371;p=linux-beck.git

Input: ati_remote2 - return the error code from sysfs channel_mask store

If the channel_mask setup fails when configuring it through sysfs,
return the error code to the caller instead of claiming success.
