Message-Id: <0d2cf8f5aab358c897902ebad40fa4edd1b4556e.1349554106.git.len.brown@intel.com> Date: Sat, 6 Oct 2012 16:09:40 -0400 From: Len Brown <lenb@...nel.org> To: linux-acpi@...r.kernel.org, linux-pm@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Mika Westerberg <mika.westerberg@...ux.intel.com>, Len Brown <len.brown@...el.com> Subject: [PATCH 19/49] ACPI: introduce module_acpi_driver() helper macro From: Mika Westerberg <mika.westerberg@...ux.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).
