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

tty: mmc: sdio: use bool for cts and remove parentheses

2025-03-17T10:22:06+00:00

'cts' in sdio_uart_check_modem_status() is considered a 'bool', but typed as signed 'int'. Make it 'bool' so it is clear the code does not care about the masked value, but true/false.

tty_operations::send_xchar is one of the last users of 'char' type for characters in the tty layer. Convert it to u8 now.

tty: mmc: sdio_uart: switch sdio_in() to return u8

2023-12-08T11:02:37+00:00

sdio_in() returns a value returned from sdio_readb(). The latter returns u8. So should the former. Therefore, switch sdio_in() return type to u8 and all its callers too.
