Subject: [PATCH 0/4] i.MX6 sleep while atomic bugfix
Date: Fri, 15 Jan 2016 19:56:46 +0100	[thread overview]
Message-ID: <1452884210-11359-1-git-send-email-l.stach@pengutronix.de> (raw)

There have been some reports about a possible scheduling while atomic bug
in the i.MX6 PCIe host driver, like the following one
https://bugzilla.kernel.org/show_bug.cgi?id=100031

Although there were some proposed patches, they all had some flaws, which
lead to none of them being included in the mainline kernel. The following
patch series fixes this bug in a proper way, instead of papering over the
problem, making the fix a bit bigger.

Regards
Lucas
