Helps keep messages off of (serial) console when
that is desired.

Isn't /proc/sys/kernel/print exactly for this purpose? At least I recall
using it.
I just wanted to hide some ath10k logs from the console, not all
system logs. I don't think that /proc/sys/kernel/print has any
granularity?
It should be based on KERN_ log levels. I don't know what your kernel
does, but ath10k should be printing only very few messages with level
KERN_INFO or above, all of of the debug messages. So you should be
easily able to filter out all ath10k debug messages as they are sent
with KERN_DEBUG.
I originally added this when I was testing .11r associating timing. Just
having a few lines of ath10k printk on the serial console added several 10s
of milliseconds to the time it took to associate, and that was throwing off my
results. I still wanted to see the messges in 'dmesg', just not on the console.
I did not want to hide other WARN level logs from the console, just the ath10k
ones.
Thanks,
Ben
