Re: [PATCH 1/2] octeontx2-vf: fix bitmap leak

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.
