The original iuutool author is Juan Carlos Borrás - fix the spelling. Signed-off-by: Thorsten Blum Signed-off-by: Johan Hovold

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

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: Make ->set_termios() old ktermios const

2022-08-30T12:22:35+00:00

There should be no reason to adjust old ktermios which is going to get discarded anyway. Reviewed-by: Andy Shevchenko Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20220816115739.10928-8-ilpo.jarvinen@linux.intel.com Signed-off-by: Greg Kroah-Hartman

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: iuu_phoenix: remove redundant variable 'error'

2021-04-01T07:53:14+00:00

The variable error is initialized to 0 and is set to 1 this value is never read as it is on an immediate return path. The only read of error is to check it is 0 and this check is always true at that point of the code. The variable is redundant and can be removed.

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().

USB: serial: iuu_phoenix: fix DMA from stack

2021-01-04T15:30:09+00:00

Stack-allocated buffers cannot be used for DMA (on all architectures) so allocate the flush command buffer using kmalloc(). Fixes: 60a8fc017103 ("USB: add iuu_phoenix driver") Cc: stable # 2.6.25 Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold
