Subject: [PATCH 07/14] ARM: pci: Allow passing per-controller private data
Date: Wed, 9 Jan 2013 21:43:07 +0100 [thread overview]
Message-ID: <1357764194-12677-8-git-send-email-thierry.reding@avionic-design.de> (raw)
In-Reply-To: <1357764194-12677-1-git-send-email-thierry.reding@avionic-design.de>
In order to allow drivers to specify private data for each controller,
this commit adds a private_data field to the struct hw_pci. This field
is an array of nr_controllers pointers that will be used to initialize
the private_data field of the corresponding controller's pci_sys_data
structure.
