Subject: Re: [PATCH v5] ptp: ocp: add Adva timecard support

Hi Vadim,
Sorry but I was on vacation for the last two weeks.
So What should I do now:
1) Do you want me to set my changes into the main linux git tree:
    git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
    and use  use '[PATCH v6] ...' prefix
2) Or
    set my changes into the net-next git tree:
    git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git
    and use  use '[PATCH net-next v6] ...' prefix

BR,
Sagi
