From 6761dd3185a76c5d9ae0141e08f123d97d7f303b Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Mon, 23 Mar 2015 11:10:32 +0000 Subject: drm/i915/skl: Extract tile height code into a helper function It will be used in a later patch and also convert all height parameters from int to unsigned int. v2: Rebased for fb modifiers. v3: Fixed v2 rebase. v4: * Height should be unsigned int. * Make it take pixel_format for consistency and simplicity.
