This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 9ddc486aa09a3413a6c492fcf160ce61bfccb7b1 ]
It is observed that, we are disabling the packet log if we write same
value to the pktlog_filter for the second time. Always enable pktlogs
on non zero filter.
Fixes: 90174455ae05 ("ath10k: add support to configure pktlog filter")
