crypto: stm32 - Remove redundant dev_err()

2026-07-27T00:29:27+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_threaded_irq() automatically logs detailed error messages on failure. Remove the now-redundant driver-specific dev_err() calls. Signed-off-by: Pan Chuang Acked-by: Maxime Méré Signed-off-by: Herbert Xu

crypto: stm32 - use list_first_entry_or_null to simplify cryp_find_dev

2026-03-27T09:52:43+00:00

Use list_first_entry_or_null() to simplify stm32_cryp_find_dev() and remove the now-unused local variable 'struct stm32_cryp *tmp'. Signed-off-by: Thorsten Blum Reviewed-by: Kees Cook Signed-off-by: Herbert Xu

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. 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

crypto: stm32 - Replace min_t(size_t) with just min()

2026-01-31T02:52:30+00:00

In most cases, min_t(size_t) and explicit casting are unnecessary because the values ->hw_blocksize, ->payload_{in,out}, and ->header_in are already of type 'size_t'. Use the simpler min() macro instead. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: stm32 - Remove unnecessary checks before calling memcpy

2026-01-30T08:09:32+00:00

memcpy() can be safely called with size 0, which is a no-op. Remove the unnecessary checks before calling memcpy(). Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu
