Hi Kalle & Carl,
Thanks for adding me to CC, I didn't receive the original patch (@Carl
maybe check your email setup why I didn't get that one?).
I've reverted the previous patch "fix WCN6750 firmware crash" in my
branch and applied this one and everything still looks fine. Thanks!
Tested-by: Luca Weiss <luca.weiss@xxxxxxxxxxxxx>
Regards
Luca
