Subject: Re: [PATCH 2/2] rtc: bd70528: Fix hour register mask

Hello Alexandre,

I'd expect the BD71828 support to still take a while. I don't expect it
to land in next kernel release. I'd prefer getting this fix in now (and
I hope it might also get merged to earlier releases by the 'fixes'
tag). So if it's not a problem for you then please apply this fix now -
I can rebase the BD71828 support when this fix is out :)

Br,
	Matti Vaittinen
