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.
