Subject: [PATCH 19/49] ACPI: introduce module_acpi_driver() helper macro
Date: Sat,  6 Oct 2012 16:09:40 -0400	[thread overview]
Message-ID: <0d2cf8f5aab358c897902ebad40fa4edd1b4556e.1349554106.git.len.brown@intel.com> (raw)
In-Reply-To: <1349554210-29978-1-git-send-email-lenb@kernel.org>
In-Reply-To: <a950c135e5b2be6ef7518d54d98a7901db1b377a.1349554105.git.len.brown@intel.com>

From: Mika Westerberg <mika.westerberg@linux.intel.com>

Add a helper macro module_acpi_driver() which reduces the boilerplate code
for ACPI drivers. This is similar what is done for other busses (PCI, SPI,
I2C etc).
