    ARM: config: sort select statements alphanumerically · b1b3f49c

    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.)
