Subject: [PATCH v2 4/4] Input: sun4i-ps2 - Fix handling of platform_get_irq() error
Date: Fri, 28 Aug 2020 16:57:44 +0200 [thread overview]
Message-ID: <20200828145744.3636-4-krzk@kernel.org> (raw)
In-Reply-To: <20200828145744.3636-1-krzk@kernel.org>
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: e443631d20f5 ("Input: serio - add support for Alwinner A10/A20 PS/2 controller")
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
