MISRA C Rule 20.12 states: "A macro parameter used as an operand to the # or ## operators, which is itself subject to further macro replacement, shall only be used as an operand to these operators". In this case, builds where CONFIG_COMPAT=y the fpu_ctxt macro is used both as a regular macro argument and as an operand for stringification in the expansion of CHECK_FIELD_. This is deviated using a SAF-x-safe comment. No functional change. Signed-off-by: Nicola Vetrini <nicola.vetrini@bugseng.com> Acked-by: Jan Beulich <jbeulich@suse.com>
