MISRA Rule 13.6 doesn't like having an expression in a sizeof() which

Address several violations by pulling the expression out into a local

No functional change.

Misra won't like the var's name matching the macro's. Can we go with just
"info"?

Ah - missed that.

I can name it to just info, but I considered "struct pirq *info" to be a
little odd.

The local variable is a non-callable entity;
"clashes" between function-like macros and non-callable entities
will be deviated (as agreed during MISRA meetings).
