Subject: [PATCH 4.9 08/44] power: supply: axp288_charger: Fix unchecked return value
Date: Mon, 20 May 2019 14:13:57 +0200 [thread overview]
Message-ID: <20190520115232.016025272@linuxfoundation.org> (raw)
In-Reply-To: <20190520115230.720347034@linuxfoundation.org>
From: Gustavo A. R. Silva <gustavo@embeddedor.com>
commit c3422ad5f84a66739ec6a37251ca27638c85b6be upstream.
Currently there is no check on platform_get_irq() return value
in case it fails, hence never actually reporting any errors and
causing unexpected behavior when using such value as argument
for function regmap_irq_get_virq().
Fix this by adding a proper check, a message reporting any errors
and returning *pirq*
Addresses-Coverity-ID: 1443940 ("Improper use of negative value")
Fixes: 843735b788a4 ("power: axp288_charger: axp288 charger driver")
