[PATCH 4.5 26/88] clk: xgene: Add missing parenthesis when clearing divider value

[Greg Kroah-Hartman]

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Loc Ho <lho@xxxxxxx>

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.
