4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Loc Ho <lho@apm.com>
commit 0f4c7a138dfefb0ebdbaf56e3ba2acd2958a6605 upstream.
In the initial fix for non-zero divider shift value, the parenthesis
was missing after the negate operation. This patch adds the required
parenthesis. Otherwise, lower bits may be cleared unintentionally.
