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

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

From: Sergei Shtylyov <redacted>

commit 2e9dcdae4068460c45a308dd891be5248260251c upstream.

In case CLK_GATE_HIWORD_MASK flag is passed to clk_register_gate(), the bit #
should be no higher than 15, however the corresponding check is obviously off-
by-one.

Fixes: 045779942c04 ("clk: gate: add CLK_GATE_HIWORD_MASK")
