Subject: [PATCH 3/6] pci: mvebu: use of_get_available_child_count()
Date: Wed, 23 Sep 2015 18:17:37 +0100	[thread overview]
Message-ID: <E1Zenfl-0004dB-HA@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20150923171706.GL21084@n2100.arm.linux.org.uk>

Rather than open-coding of_get_available_child_count(), use the provided
helper instead.
