Subject: [PATCH V6 01/11] ACPI: introduce .match() callback for ACPI scan handler
Date: Thu, 15 May 2014 14:44:06 +0800 [thread overview]
Message-ID: <1400136256-2218-2-git-send-email-rui.zhang@intel.com> (raw)
In-Reply-To: <1400136256-2218-1-git-send-email-rui.zhang@intel.com>
Currently, ACPI scan handler uses strcmp() to match device ids
and scan handler ids.
When converting PNPACPI enumeration into a scan handler, which I will do
later in this patch set, the current code becomes not flexible enough
because ACPI pnp scan handler requires wildcase and case insensitive support.
Thus a per scan handler .match() callback is introduced in this patch,
so that specified scan handler can have more flexible matching mechanism
by introduce its own .match() callback.
