Subject: [16/59] hwmon: (pc87360) Fix device resource declaration
Date: Tue, 24 Aug 2010 15:24:28 -0700	[thread overview]
Message-ID: <20100824222523.804429703@clark.site> (raw)
In-Reply-To: <20100824224625.GA5449@kroah.com>

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jean Delvare <khali@linux-fr.org>

commit b9783dcebe952bf73449fe70a19ee4814adc81a0 upstream.

It's not OK to call platform_device_add_resources() multiple times
in a row. Despite its name, this functions sets the resources, it
doesn't add them. So we have to prepare an array with all the
resources, and then call platform_device_add_resources() once.

Before this fix, only the last I/O resource would be actually
registered. The other I/O resources were leaked.
