From 5a8888a3119eb5b67f6e90605be9ed2e04807126 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 22 Jan 2015 12:48:33 +0200 Subject: [PATCH] drm/radeon: Don't increment pipe_id in kgd_init_pipeline This patch fixes the behavior of kgd_init_pipeline in that this function shouldn't automatically increase the pipe_id argument by 1 right at the start of the function. This is because the first_pipe value might not be always 1, and because a proper interface function should not hide this info inside its implementation. In other words, the calling function should provide the real pipe_id and not count on kgd_init_pipeline to "fix" it.
