Subject: drivers/rtc/rtc-ds3232.c: make it possible to share an irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a8a15eb19d885bec172c396178c148264987922f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/rtc/rtc-ds3232.c: make it possible to share an irq

It's possible to have RTC irq shared with other device (e.g.  t4240qds
board shares ds3232irq with phy one).  Handle this in driver.
