From 81db38027d5c7b1cb13ea34f7030bb4467487d4f Mon Sep 17 00:00:00 2001

Subject: [PATCH 1237/1565] drm/amd/dal: disable BM calcs log by default
It is only related to verbose output, not for
errors.
Also, do not output anything in case logger
buffer is empty. This will remove empty DRM
output case nothing was added to buffer
after dal_logger_open.
This could happen in case dal_logger_close was
called just after dal_logger_open, or when log
major/minor disabled
