4.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anilkumar Kolli <ako...@qti.qualcomm.com>
commit 9ddc486aa09a3413a6c492fcf160ce61bfccb7b1 upstream.
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")
