From: Tomi Valkeinen Date: Thu, 4 Jun 2015 11:12:16 +0000 (+0300) Subject: OMAPDSS: remove uses of __init/__exit X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ede9269572da9206249f02ebe031ded025b84fd3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git OMAPDSS: remove uses of __init/__exit The following patches will add component handling to omapdss, improving the handling of deferred probing. However, at the moment we're using quite a lot of __inits and __exits in the driver, which prevent normal dynamic probing and removal. This patch removes most of the uses of __init and __exit, so that we can register drivers after module init, and so that we can unregister drivers even if the module is built-in.
