Perhaps using the function name _dev_info() and adding
the macro above is an acceptable workaround until the
dev_info struct names or local variable names could be
renamed if necessary.

dev_err and dev_warn exist in source comments only and
don't seem to be a problem.

of dev_info local variables and structs?
