Subject: gpio: bcm-kona: fix bcm_kona_gpio_reset() warnings
From: Ben Dooks <ben.dooks@xxxxxxxxxxxxxxx>
commit b66b2a0adf0e48973b582e055758b9907a7eee7c upstream.
The bcm_kona_gpio_reset() calls bcm_kona_gpio_write_lock_regs()
with what looks like the wrong parameter. The write_lock_regs
function takes a pointer to the registers, not the bcm_kona_gpio
structure.
Fix the warning, and probably bug by changing the function to
pass reg_base instead of kona_gpio, fixing the following warning:
drivers/gpio/gpio-bcm-kona.c:550:47: warning: incorrect type in argument 1
(different address spaces)
expected void [noderef] <asn:2>*reg_base
got struct bcm_kona_gpio *kona_gpio
warning: incorrect type in argument 1 (different address spaces)
expected void [noderef] <asn:2>*reg_base
got struct bcm_kona_gpio *kona_gpio
