Subject: drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b3288a43b4dacd2b4d2b24726d7b469d8ade5120;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled

When the clock is disabled, do not return a rate of 0 but instead return
the rate the clock will be running at after it gets enabled.  This
prevents problems when the core clock code is trying to determine a
suitable rate, while the clock is still off.
