Message-ID: <2117188.iNXM1T8hb3@phil> Date: Fri, 06 Mar 2015 10:52:39 +0100 From: Heiko Stuebner <heiko@...ech.de> To: akpm@...ux-foundation.org, Alessandro Zummo <a.zummo@...ertech.it> Cc: rtc-linux@...glegroups.com, linux-kernel@...r.kernel.org 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.
