| | | | | | | | | | | | | | | ieee754d.o contains only debug code and dp_sqrt.o and sp_sqrt.o contain code which for MIPS I/II/III systems we don't want to link.

It's a bit larger than is good for this point in the cycle but it's all for a newly added driver so not so worrying as it might otherwise be. Some of it's integration problems, some of it's the sort of problem usually turned up in stress tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race between sst_byt_stream_free() and sst_byt_get_stream() if sst_byt_get_stream() called from sst_byt_irq_thread() context is accessing the byt->stream_list while a stream is deleted from the list. A stream is added to byt->stream_list in sst_byt_stream_new() and deleted in sst_byt_stream_free(). sst_byt_get_stream() is always protected by sst->spinlock, but the stream addition and deletion are not protected. The patch adds spinlock to both stream addition and deletion.

This causes problems for the "Speaker Switch" control, which will report an error if the CODEC is suspended because it relies on a volatile register. To resolve this issue mark CLASS_D_CONTROL_1 as non-volatile and manually keep the register cache in sync by updating both bits when changing the mute status.
