From b45203004ec3f3e5a259e68eddb3eb572d37f56d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 12 Sep 2020 12:28:47 -0600 Subject: log: Add a flag to enable log drivers At present there is no way to disable a log driver. But the syslog driver causes (attempted) network traffic in sandbox every time a log message is printed, which is often. Add a flag to enable a log driver. Adjust struct log_device to use a short for next_filter_num so that no more memory is used for devices. Also fix a missing line in the struct log_driver comment while here. To maintain compatibility, enable it for all drivers for now.
