Subject: [PATCH 5.4 085/142] gpio: bcm-kona: Fix return value of bcm_kona_gpio_probe()

From: Tiezhu Yang <yangtiezhu@...ngson.cn>

[ Upstream commit 98f7d1b15e87c84488b30ecc4ec753b0690b9dbf ]

Propagate the error code returned by devm_platform_ioremap_resource()
out of probe() instead of overwriting it.

Fixes: 72d8cb715477 ("drivers: gpio: bcm-kona: use devm_platform_ioremap_resource()")
