From 66dde584a00769aa67865ea019152205bf28d970 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Tue, 17 Feb 2015 23:18:40 +0100 Subject: [PATCH] rtc: hym8563: 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.
