From df1d7dcf1eafe37732adedd160d31354d6d7de9d Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 4 Dec 2007 14:44:05 +0100 Subject: [PATCH] hwclock: check for ENODEV /sbin/hwclock is supposed to fall back to using /dev/rtc0 if /dev/rtc isn't working (which it isn't, because mkinitrd creates it with the old device numbers, and we're switching to the new RTC_CLASS driver). Unfortunately, it'll only cope if the error it gets is ENOENT (i.e. the device node doesn't exist). It doesn't fall back to the next device in the list if the error is ENODEV, which is what happens when the device node exists, but there's no driver.
