Subject: Re: Nokia n900 problems in 3.18-rc1 (was Re: USB Ethernet gadget on
Nokia n900)
Hi!
I tried enabling audio. It works ...sometimes... after fixing
kconfig. But I'm getting WARN_ON, about 50% of time. Ideas welcome.

commit 85a6aea58dbfe1068098d4160c17d3dad530ea50
Author: Pavel <pavel@....cz>

Nokia N900 audio driver should be selectable even without RX51 support
enabled (as is the case with RX51 booting using device tree).
