Subject: [PATCH] busybox: add ts72xx hwclock-default file and modify
 hwclock.sh
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This patch simplifies the hwclock.sh init script and adds a possibility to
fallback to default RTC device even if the device specified in HWCLOCKDEVICE
doesn't exist.
