Subject[PATCH v2 2/4] Input: omap4-keypad - Fix handling of platform_get_irq() error
Date
platform_get_irq() returns -ERRNO on error.  In such case comparison
to 0 would pass the check.

Fixes: f3a1ba60dbdb ("Input: omap4-keypad - use platform device helpers")
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
