Subject: [PATCH v2 0/2] dmaengine: cppi41: PM runtime fixes
Date: Mon, 9 Jan 2017 18:03:35 +0100 [thread overview]
Message-ID: <20170109170337.6957-1-abailon@baylibre.com> (raw)
I have tried to play music on usb headset on BeagleBone Black

Note that with this series, I'm able to play music again but
I have a lot of underruns. These underruns doesn't happens when
the dma is not enabled.
Changes in v2:
- remove the condition and use list_empty to set the variable "active"
Alexandre Bailon (2):
dmaengine: cppi41: Fix list not empty warning on runtime suspend
dmaengine: cppi41: Ignore EINPROGRESS for PM runtime in interrupt
handler
