Subject: [PATCH] gpio: regmap: fix type clash
Date: Sun, 26 Jul 2020 01:23:37 +0200 [thread overview]
Message-ID: <20200725232337.27581-1-michael@walle.cc> (raw)
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")
Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Michael Walle <michael@walle.cc>
