[Qemu-devel] [PATCH] ahci: fix ICC mask definition


From: John Snow
Subject: [Qemu-devel] [PATCH] ahci: fix ICC mask definition
Date: Tue, 21 Jul 2015 14:02:01 -0400

There are likely others that could be updated, but we'll
go with a light touch for 2.4 for now.

Without the Unsigned specifier, this shifts bits into the
signed bit, which makes clang unhappy and could cause
unwanted behavior.
