From: Ben Skeggs Date: Fri, 22 Mar 2013 00:05:03 +0000 (+1000) Subject: drm/nouveau/mc: handle irq-related setup ourselves X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0fa9061ae8c10a9178d696cf48d94c3bf2848f9f;p=linux-beck.git drm/nouveau/mc: handle irq-related setup ourselves We need to be able to process interrupts before the DRM code is able to actually enable them, set it up ourselves. Also, it's less convoluted to *not* use the DRM wrappers it appears...
