Hi all,
Commit 412e60373245 ("spi: core: avoid waking pump thread from spi_sync
instead run teardown delayed") caused a PM regression in Linux next
where a SPI device (drivers/spi/spi-omap2-mcspi.c) no longer idles
for PM runtime.
Looks like this also breaks suspend as reported at [0].
Regards,
Tony

Oh and looks like Jon already also came to the conclusion
that PM runtime is now broken at [1]. Sorry forgot to add
Jon to Cc earlier, added now.
