So allocate it with devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID). This avoids the need of the VLAN_BITMAP_SIZE macro which: - needlessly has a 'nic_dev' parameter - should be "long" (and not byte) aligned, so that the bitmap semantic is respected This is in fact not an issue because VLAN_N_VID is 4096 at the time being, but devm_bitmap_zalloc() is less verbose and easier to understand.
