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.

Perhaps the . before the [ might be a bit broad.

I'm not sure there's a great way to handle this.

At this point preceding spaces and parentheses are removed, probably any
alphanumeric symbol should fit here.

OTOH I believe in correct C code here before \[ symbol you may find only
an alphanumeric symbol or ^, so I don't expect any false negatives, if .
is used above.

I tested this version (COMPLEX_MACRO only) with . symbol over all .c and
.h files in the kernel (commit ce5c2d2c256a4) and the change fixes 230
false positives, see the list below in format $file:$lineno.

No new false negatives are introduced, so according to my test . is okay
here to have.

Please also note that the problem is quite old and it emerged earlier,
e.g. see http://permalink.gmane.org/gmane.linux.ports.arm.kernel/451646 etc.
