Subject: [PATCH 8/9] platform/x86: hp-wmi: Do not shadow errors in sysfs show functions
Date: Wed, 19 Apr 2017 19:25:20 -0700 [thread overview]
Message-ID: <45e338841cbfe6ad21ec277a0c0974a3e532c07d.1492654448.git.dvhart@infradead.org> (raw)
In-Reply-To: <cover.1492654448.git.dvhart@infradead.org>
In-Reply-To: <cover.1492654448.git.dvhart@infradead.org>
From: "Darren Hart (VMware)" <dvhart@infradead.org>
The new hp_wmi_read_int function returns a negative value in case of
error, pass this on directly rather than always replacing it with
-EINVAL.
Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>
