Whenever there is a division it is usually worthwhile to
add some belt'n'braces code to ensure that cnt != 0, otherwise
a machine signal can occur.

This is not acceptable.
Your conditional expression is not spaced properly, there must be a space
between "if" and the openning parenthesis of the condition.
You also must properly re-indent the statement the new if() condition
is protecting.
Hello.

Space needed after *if*. Please run your patches thru
scripts/checkpatch.pl before posting.

What happens to 'tc_cfg->bwg_percent' when cnt == 0?
You need to indent this line by an extra TAB, since it's a part of the
*if* statment now.
