From a9dbe558920e12ea286cd4479039df26991a95de Mon Sep 17 00:00:00 2001 From: Thomas Koeller Date: Wed, 2 Jun 2010 15:53:05 +0200 Subject: rtc: rs5c372: r2025: fix check for 'oscillator halted' condition The R2025SD chip, according to its data sheet, sets the /XST bit to zero if the oscillator stops. Hence the check for this condition was wrong.
