Subject: drm: Enable pr_debug() for drm_printer
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=79a5ad2fdb3cb48e9c4e9d0d7688f0401cdb85d5;p=openwrt%2Fstaging%2Fblogic.git

drm: Enable pr_debug() for drm_printer

pr_debug() is conditionally compiled and requires either
dynamic-debugging to be enabled or for the code to opt-in using #define
DEBUG. Since drm_print provides a central debugging facility using
pr_debug(), make sure it will always produce output.
