Pull Microchip clock fixes from Claudiu Beznea: - Fix the GMAC GCLK clock ID for the SAM9X7 SoC - Properly decrement the reference count of a struct device_node in pmc_register_ops() after it is no longer needed - Fix the MPFS peripheral driver registration failures by using the proper size and mapping for the output clocks array [sboyd@kernel.org: These all look non-critical so not taking for clk-fixes] * tag 'clk-microchip-fixes-7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux: clk: at91: keep securam node alive while mapping it clk: microchip: mpfs-ccc: fix peripheral driver registration failures after oob fix clk: at91: sam9x7: Fix gmac_gclk clock definition

clk: at91: keep securam node alive while mapping it

2026-05-31T14:17:55+00:00

pmc_register_ops() gets an owned reference to the "atmel,sama5d2-securam" node with of_find_compatible_node(). The success path dropped that reference before passing the node to of_iomap(), leaving of_iomap() to consume a node pointer after the caller had released its reference. Move of_node_put() after of_iomap() so the node remains referenced for the mapping operation. The unavailable-node error path already releases the reference.

clk: at91: sam9x7: Fix gmac_gclk clock definition

2026-05-16T16:47:09+00:00

According to the datasheet (see link section), table 12.1, instance ID 24 is used for the GMAC generic clock, while instance ID 67 is reserved. Add the correct gmac_gclk entry at ID 24, aligned with the SoC clock layout, and remove the old misplaced entry at ID 67.

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
