Use this small script to replace CamelCase and wrong case
on vars:

<script>
FILES=$(find "$1" -type f|grep -e '.c$' -e '.h$')
CAMEL_VARS=$(cat tags|perl -ne 'print "$1\n" if (m/^(\w*[A-Z]\w*[a-z]\w*)\s/)')
for i in $CAMEL_VARS; do
        new=$(perl -e '
                my $s = $ARGV[0];
                $s =~ s{([^a-zA-Z]?)([A-Z]*)([A-Z])([a-z]?)}{
                        my $fc = pos($s)==0;
                        my ($p0,$p1,$p2,$p3) = ($1,lc$2,lc$3,$4);
                        my $t = $p0 || $fc ? $p0 : '_';
                        $t .= $p3 ? $p1 ? "${p1}_$p2$p3" : "$p2$p3" : "$p1$p2";
                        $t;
                }ge;
                print $s;' "$i")
        for j in $FILES; do
                sed -E "s,\b$i\b,$new,g" -i $j
        done
done
for i in $(git grep "#define zr" drivers/staging/media/zoran/*.[ch]|perl -ne 'print "$1\n" if (m/#define\s+(zr\S+)/)'); do j=$(echo $i|tr [a-z] [A-Z]); sed "s,\b$i\b,$j,g" -i drivers/staging/media/zoran/*.[ch]; done
</script>

This should solve almost all warnings reported by checkpatch.pl
in strict mode.
