Subject: [PATCH 5.8 297/464] gpio: regmap: fix type clash

From: Michael Walle <michael@...le.cc>

[ Upstream commit a070bdbbb06d7787ec7844a4f1e059cf8b55205d ]

GPIO_REGMAP_ADDR_ZERO() cast to unsigned long but the actual config
parameters are unsigned int. We use unsigned int here because that is
the type which is used by the underlying regmap.

Fixes: ebe363197e52 ("gpio: add a reusable generic gpio_chip using regmap")
