He is probably talking about this commit:
https://git.kernel.org/linus/a1769bb68a850508a492e3674ab1e5e479b11254
from kernel 5.6.

This was backported to version v4.19.143 and v4.14.196 some days ago.

The problem affects ath10k-ct in all versions (18.06, 19.07 and master)
and ath10k in 19.07 and 18.06.
