Regression in Linux next with SPI pump changes

[Tony Lindgren <tony@xxxxxxxxxxx>]

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
