From 9950cda2a0187314c3cd6a86415ab9050074c5f8 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 18 Jan 2018 19:05:36 -0500 Subject: drm/amdgpu: drop the drm irq pre/post/un install callbacks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The preinstall callback didn't do anything because not all of the IPs were initialized when it was called. Move the postinstall setup into sequence in the driver. The uninstall callback disabled all interrupt source, but it got called too late in the driver sequence and caused problems with IPs who already freed the relevant data structures. Move the call into the right place in the driver sequence.
