[BusyBox] hwclock problem in 1.00-rc2

[Wang Jian]

Hi Sauder, Vernon,

Thanks for your information.

I read the customized RTC driver's dirty source code (which is not
written by me), and find a lot of errors in it. I did a quick hack and
it works now.

It seems that I should rewrite a driver from scratch for long term.
