A simple search over the kernel souce displays a number of correctly defined multiline macro, which generally are used as an array element initializer: % find ../linux -type f | xargs grep -B1 -H '^[:space]*\[.*\\$' However checkpatch.pl unexpectedly complains about all these macro definitions: % ./scripts/checkpatch.pl --types COMPLEX_MACRO -f include/linux/perf/arm_pmu.h ERROR: Macros with complex values should be enclosed in parentheses +#define PERF_MAP_ALL_UNSUPPORTED \ + [0 ... PERF_COUNT_HW_MAX - 1] = HW_OP_UNSUPPORTED The change intends to fix this type of false positives by flattening only array members and skipping array element designators.
