Subject: [PATCH 12/13] eeepc-laptop: store_cpufv: return error if set_acpi fails
Date: Sat, 13 Sep 2014 01:06:51 +0200 [thread overview]
Message-ID: <1410563212-31565-13-git-send-email-fransklaver@gmail.com> (raw)
In-Reply-To: <1410563212-31565-1-git-send-email-fransklaver@gmail.com>
The result of set_acpi is left unchecked, but it may return errors. If
one occurs, send the error to the caller.
