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

clk: davinci: Add NULL check in davinci_lpsc_clk_register()

2025-06-19T23:48:09+00:00

devm_kasprintf() returns NULL when memory allocation fails. Currently, davinci_lpsc_clk_register() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue and ensuring no resources are left allocated.

clk: davinci: remove support for da830

2025-03-13T20:17:41+00:00

This SoC has some leftover code all over the kernel but no boards are supported anymore. Remove support for da830 from the davinci clock driver. With it: remove the ifdefs around the data structures as the da850 remains the only davinci SoC supported and the only user of this driver.

clk: Use device_get_match_data()

2023-10-24T03:16:21+00:00

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.

Commit 7dd33764486d ("ARM: davinci: Delete DM644x board files") and commit b4aed01de486 ("ARM: davinci: Delete DM646x board files") removes the support for DaVinci DM644x and DM646x boards. Hence, remove the PLL and PSC clock descriptions for those boards as well.
