hwmon: (ltc4282) Make sure clk_init_data is fully initialized
Description

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.
