Problems with Data Types, Medium Severity (1)

pci.h
[+] struct pci_dev (1)

	Change	Effect
1	Field module_alias has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
