PCI core, after pcim_enable_device(), takes care about the allocated

Instead of commit 21aa3983d619 I guess this patch is more around my commit 9be8bc4dd617 ("i2c: designware-pci: Fix BUG_ON during device removal")? But still I don't think it qualifies Fixes tag?

I was curious to see would this patch bring back above BUG_ON and fortunately not (rmmod/modprobe i2c_designware_pci on MSI enabled instance):-)
