clk: visconti: Make sure clk_init_data is fully initialized

2026-08-20T05:57:32+00:00

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. visconti_clk_register_gate() 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.

clk: visconti: pll: use kzalloc_flex

Simplify allocation by using a flexible array member and kzalloc_flex. Add __counted_by for extra runtime analysis. Assign after allocation as required by __counted_by. Signed-off-by: Rosen Penev Reviewed-by: Brian Masney Acked-by: Nobuhiro Iwamatsu Signed-off-by: Stephen Boyd

clk: visconti: pll: initialize clk_init_data to zero

2026-04-12T00:55:27+00:00

Sashiko reported the following: > The struct clk_init_data init is declared on the stack without being > fully zero-initialized. While fields like name, flags, parent_names, > num_parents, and ops are explicitly assigned, the parent_data and > parent_hws fields are left containing stack garbage. clk_core_populate_parent_map() currently prefers the parent names over the parent data and hws, so this isn't a problem at the moment. If that ordering ever changed in the future, then this could lead to some unexpected crashes. Let's just go ahead and make sure that the struct clk_init_data is initialized to zero as a good practice.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
