From 523313092abffb21bfe7cd8d37615402b2228850 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Wed, 15 Aug 2012 19:23:25 +0100 Subject: [PATCH] drm/i915: Don't hardcode the number of pipes in the error state dump New-ish devices have 3 pipes, so let's not just hardcode 2 but use the for_each_pipe() macro and make struct intel_display_error_state is big enough.
