From: Eric Anholt Date: Wed, 20 Feb 2019 21:03:38 +0000 (-0800) Subject: drm/vc4: Use drm_print_regset32() for our debug register dumping. X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3051719af11eb48dc8947826cfb66dbe0f281c7d;p=openwrt%2Fstaging%2Fblogic.git drm/vc4: Use drm_print_regset32() for our debug register dumping. This removes a bunch of duplicated boilerplate for the debugfs vs runtime printk debug dumping.
