This patch series resolves a problem with S_HW_FREQ_SEEK when called in
non-blocking mode. Currently this would actually block during the seek.
This is not a good idea. This patch changes the spec and the drivers to
return -EAGAIN when called in non-blocking mode.
In the future actual support for non-blocking mode might be added to
selected drivers, but that will require a new event (SEEK_READY or something
like that), and I am not convinced it is worth the effort anyway.
Regards,
Hans
