Commit 7ff9554bb5 ("printk: convert byte-buffer to variable-length
record buffer") removed start and end parameters from
call_console_drivers, but those parameters still exist in
include/trace/events/printk.h.
Without start and end parameters handling, printk tracing became more
simple as: trace_console(text, len);
