Yonattan Louise 63e3a4e772 Fix checkpatch issue - ERROR:ELSE_AFTER_BRACE
The 'else' statement should be in the same line that the
close brace of the 'if' statement. E.g.:

	if (condition) {
		do_this();
		do_that();
	} else {
		otherwise();
	}

This commit fixed this kind of error using the following script:

	#!/bin/bash

	for file in $(find ./ -name "*.[ch]" ! -path "./scripts/*" ! -path "./host/src/wrsconfig/*");
	do
		if [ ! -h $file ];
		then
			sed -i '/^[ \t]*}$/ {
	:review_next_one_too
	N
	s/^\(.*\)\n[ \t]*else/\1 else/
	/}$/ b review_next_one_too
	}' $file;

		fi;
	done
