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

soc: imx8m: Fix error handling for clk_prepare_enable()

2026-01-18T02:33:42+00:00

imx8m_soc_prepare() directly returns the result of clk_prepare_enable(), which skips proper cleanup if the clock enable fails. Check the return value of clk_prepare_enable() and release resources if failure.

soc: imx8m: Dump higher 64bits UID

2025-05-09T10:16:28+00:00

i.MX8MP UID is actually 128bits and partitioned into two parts. The 1st 64bits are at 0x410 and 0x420, and 2nd 64bits are at 0xE00 and 0xE10. Dump the whole 128bits for i.MX8MP, by set soc_uid as an array with two u64. Signed-off-by: Peng Fan Reviewed-by: Marco Felsch Signed-off-by: Shawn Guo

Cleanup code by introducing soc_uid hook, i.MX8MQ/M/N could reuse one function imx8m_soc_uid, i.MX8MP could have its own one. With this patch, it will easy to add 128bits UID support for i.MX8MP. Signed-off-by: Peng Fan Reviewed-by: Marco Felsch Signed-off-by: Shawn Guo

soc: imx8m: Cleanup with adding imx8m_soc_[un]prepare

2025-05-09T10:16:28+00:00

There is a common flow to i.MX8M family, map OCOTP register base and enable ocotp clk first before read Unique ID from OCOTP. So introduce imx8m_soc_prepare to do ioremap and enable the ocotp clk, and introduce imx8m_soc_unprepare to disable the clk and do iounmap. With this patch, no need to spread the ioremap and clk handling in each soc_revision hook. Signed-off-by: Peng Fan Reviewed-by: Marco Felsch Signed-off-by: Shawn Guo
