[PATCH] clk: qcom: Fix a possible NULL pointer dereferencing

From: Vivek Gautam
Date: Thu Jan 05 2017 - 03:57:15 EST


Assign num_parents as 0 while registering fixed rate clocks
in _qcom_cc_register_board_clk(), to make sure the clk framework
doesn't dereference parent.

Fixes: ee15faffef11 ("clk: qcom: common: Add API to register board clocks backwards compatibly")
