Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

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

drivers/usb/serial: refactor min with min_t

2024-11-13T14:09:51+00:00

Ensure type safety by using min_t() instead of casted min(). Signed-off-by: Sabyrzhan Tasbolatov Link: https://lore.kernel.org/r/20241112155817.3512577-8-snovitoll@gmail.com Signed-off-by: Greg Kroah-Hartman

USB: serial: drop driver owner initialization

2024-08-26T13:28:25+00:00

Core in usb_serial_register_drivers() already sets the .owner, so driver does not need to. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Johan Hovold

USB: serial: fix tty-port initialized comments

2022-07-25T09:01:40+00:00

Fix up the tty-port initialized comments which got truncated and obfuscated when replacing the old ASYNCB_INITIALIZED flag. Fixes: d41861ca19c9 ("tty: Replace ASYNC_INITIALIZED bit and update atomically") Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold

USB: serial: use kmemdup instead of kmalloc + memcpy

2022-06-22T06:56:52+00:00

For code neat purpose, we can use kmemdup to replace kmalloc + memcpy. Signed-off-by: Slark Xiao Signed-off-by: Johan Hovold

USB: serial: replace symbolic permissions by octal permissions

2021-08-26T07:38:27+00:00

Replace symbolic permission macros with octal permission numbers because octal permission numbers are easier to read and understand instead of their symbolic macro names. No functional change. Suggested-by: Lukas Bulwahn Signed-off-by: Utkarsh Verma Signed-off-by: Johan Hovold

USB: serial: make usb_serial_driver::chars_in_buffer return uint

2021-05-19T08:56:41+00:00

tty_operations::chars_in_buffer is being switched to return uint. Do the same for usb_serial_driver's chars_in_buffer. Signed-off-by: Jiri Slaby [ johan: amend commit message ] Signed-off-by: Johan Hovold

USB: serial: make usb_serial_driver::write_room return uint

2021-05-19T08:56:40+00:00

Line disciplines expect a positive value or zero returned from tty->ops->write_room (invoked by tty_write_room). Both of them are being updated to return an unsigned int. Switch also usb_serial_driver::write_room and all its users. Signed-off-by: Jiri Slaby [ johan: amend commit message, drop unrelated comment change ] Signed-off-by: Johan Hovold

USB: serial: make remove callback return void

2021-02-09T12:13:58+00:00

All usb_serial drivers return 0 in their remove callbacks and driver core ignores the value returned by usb_serial_device_remove(). So change the remove callback to return void and return 0 unconditionally in usb_serial_device_remove().
