Subject: [PATCH 4.9 103/107] PM / clk: signedness bug in of_pm_clk_add_clks()

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

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

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 5e2e2f9f76e157063a656351728703cb02b068f1 upstream.

"count" needs to be signed for the error handling to work.  I made "i"
signed as well so they match.

Fixes: 02113ba93ea4 (PM / clk: Add support for obtaining clocks from device-tree)
