Date: Sun, 11 Oct 2015 21:35:45 -0400 From: Paul Gortmaker <paul.gortmaker@...driver.com> To: <linux-arm-kernel@...ts.infradead.org> CC: <linux-kernel@...r.kernel.org>, Paul Gortmaker <paul.gortmaker@...driver.com>, Russell King <linux@....linux.org.uk> Subject: [PATCH 1/3] amba: create builtin_amba_driver to avoid registration boilerplate In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device: better support builtin boilerplate avoidance") we introduced the builtin_driver macro. Here we use that support and extend it to amba driver registration, so where a driver is clearly non-modular and builtin-only, we can register it in a similar fashion. And existing code that is clearly non-modular can be updated with the simple mapping of module_amba_driver(...) ---> builtin_amba_driver(...) We've essentially cloned the former to make the latter, and taken out the remove/module_exit parts since those never get used in a non-modular build of the code.
