Subject: [PATCH 2/2] drm/tve200: Fix handling of platform_get_irq() error
Date: Thu, 27 Aug 2020 09:11:07 +0200 [thread overview]
Message-ID: <20200827071107.27429-2-krzk@kernel.org> (raw)
In-Reply-To: <20200827071107.27429-1-krzk@kernel.org>
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: 179c02fe90a4 ("drm/tve200: Add new driver for TVE200")
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
