The bitmap allocated with bitmap_zalloc() in otx2vf_probe() was not
released in otx2vf_remove(). Unbinding and rebinding the driver 
therefore
triggers a kmemleak warning:

    unreferenced object (size 8):
      backtrace:
        bitmap_zalloc
        otx2vf_probe

Call bitmap_free() in the remove path to fix the leak.

For reference, as a fix for code present in net, this series
should be targeted at net, like this:

Subject: [PATCH net 1/2] ...

See: https://docs.kernel.org/process/maintainer-netdev.html

Thanks for pointing this out.
I’ll resend v2 for the net tree with the correct subject prefix.

Best regards,
