From: Gianluca Luparini <gianluca.luparini@xxxxxxxxxxx>
The xen sources contains violations of MISRA C:2012 Rule 7.2 whose headline
states:
"A "u" or "U" suffix shall be applied to all integer constants that are
represented in an unsigned type".
I propose to use "U" as a suffix to explicitly state when an integer constant
is represented in an unsigned type.
For homogeneity, I also added the "U" suffix in some cases that the tool didn't
report as violations.
