Subject: lp8788-buck: fix a parent device on devm_gpio_request()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=38d8f67cb6f6d40dd9473a972ec65b3d54a785dd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

lp8788-buck: fix a parent device on devm_gpio_request()

 Use 'platform_device' rather than i2c client device node.
 Arguments are added in lp8788_init_dvs() and lp8788_dvs_gpio_request().
