Subject: Regression in Linux next with SPI pump changes
Date: Wed, 23 Jan 2019 13:56:42 -0800	[thread overview]
Message-ID: <20190123215642.GK5720@atomide.com> (raw)

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
