Reset the hw_ptr before queuing the restore_stream_context
work to eradicate a nasty white audio noise on resume.

I can't do anything with this, you've not provided a signoff for it.
Please see SubmittingPatches for what a signoff means and why it's
important.

Please also try to send your patches to relevant people - you've sent
this to the ARM kernel list but not to Vinod Koul who's the main
maintainer for the Intel drivers.
