Re: [PATCH treewide 1/5] clk: ti: Make sure clk_init_data is fully initialized

[sashiko-bot@kernel.org]

> 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.
> 
> _register_mux() fills in init.parent_data, and assumes that
> init.parent_names 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.

> Fixes: 667f420c09f1417c ("clk: ti: mux: resolve parent clocks by DT index, not by name")
> Closes: https://lore.kernel.org/CAMuHMdU3yVqoyHC4eNF2NuYo8wy+6ODLoYat4R71X99Mxc_=kw@mail.gmail.com
