As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)
