Subject: [PATCH v2 1/4] Input: ep93xx_keypad - Fix handling of platform_get_irq() error
Date: Fri, 28 Aug 2020 16:57:41 +0200 [thread overview]
Message-ID: <20200828145744.3636-1-krzk@kernel.org> (raw)
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: 60214f058f44 ("Input: ep93xx_keypad - update driver to new core support")
