Subject: checkpatch and pr_fmt()?

When using the recently introduced pr_fmt() infrastructure (commit
d091c2f58ba32029495a933b721e8e02fbd12caa, "Add 'pr_fmt()' format modifier to
pr_xyz macros."), checkpatch spits out the following annoying error:

| ERROR: Macros with complex values should be enclosed in parenthesis
| +#define pr_fmt(fmt)    "%s: " fmt, __func__

Unfortunately, adding parentheses is not a solution, as it creates illegal C
code.

With kind regards,
