Problems with Data Types, Medium Severity (4)

udev.h
[+] struct udevice (1)

	Change	Effect
1	Field event_timeout 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.

udev_rules.h
[+] struct udev_rule (3)

	Change	Effect
1	Field event_timeout 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.
2	Type of field mode has been changed from mode_t (4 bytes) to struct key (8 bytes).	1) This field may be incorrectly initialized or accessed by applications. 2) Size of the inclusive type has been changed.
3	Field mode_operation has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
