[PATCH v2 4/4] Input: sun4i-ps2 - Fix handling of platform_get_irq() error

From: Krzysztof Kozlowski
Date: Fri Aug 28 2020 - 10:58:12 EST


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")
