Subject: [PATCH RESEND 01/12] ACPI: introduce module_acpi_driver() helper macro
Date: Fri,  7 Sep 2012 10:31:38 +0300	[thread overview]
Message-ID: <1347003109-26887-2-git-send-email-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <1347003109-26887-1-git-send-email-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).
