## Overview

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (ltc4282) Make sure clk_init_data is fully initialized

The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need.  However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.

ltc428_clk_provider_setup() does not fill in any parent clocks, and
assumes that init.num_parents is NULL.  However, the latter in
uninitialized, and thus may cause a crash.

Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents.
