From: Alexandre Belloni Date: Tue, 11 Aug 2015 09:12:47 +0000 (+0200) Subject: power/reset: at91-reset: allow compiling as a module X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6e64180a7c0219d769e05b6dbe5af4a073c1eb92;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git power/reset: at91-reset: allow compiling as a module It was not possible to compile at91-reset as a module. Implement .remove() to allow it. Also switch to module_platform_driver_probe() as it is not hotpluggable.
