treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

media: dvb-usb-v2: lmedm04: Fix firmware macro definitions

2025-11-05T13:08:55Z

The firmware filename macros incorrectly included semicolons in their string literal definitions. Right now, this wasn't causing any real problem, but coming changes to the MODULE_INFO() macro make this more sensitive. Specifically, when used with MODULE_FIRMWARE(), this created syntax errors during macro expansion: MODULE_FIRMWARE(LME2510_C_S7395); expands to: MODULE_INFO(firmware, "dvb-usb-lme2510c-s7395.fw";) ^ syntax error Remove the trailing semicolons from all six firmware filename macro definitions. Semicolons should only appear at the point of use, not in the macro definition.

media: dvb-usb-v2: Constify struct i2c_algorithm

2025-02-21T09:33:14Z

'struct i2c_algorithm' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers. More over, dvb_usb_device_properties->i2c_algo seems to only be copied in i2c_adapter->algo, which is already a "const struct i2c_algorithm". This is done in dvb_usbv2_i2c_init() On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 35366 5832 36 41234 a112 drivers/media/usb/dvb-usb-v2/af9015.o After: ===== text data bss dec hex filename 35430 5768 36 41234 a112 drivers/media/usb/dvb-usb-v2/af9015.o Signed-off-by: Christophe JAILLET Signed-off-by: Hans Verkuil

media: anysee: Fix and remove outdated comment

2024-10-15T22:36:48Z

anysee driver was transformed to use usbv2 years ago. The comments in anysee_ctrl_msg() still are referencing the old interfaces where msleep() was used. The v2 interfaces also changed over the years and with commit 1162c7b383a6 ("[media] dvb_usb_v2: refactor dvb_usbv2_generic_rw()") the usage of msleep() was gone anyway. Remove FIXME comment and update also comment before call to dvb_usbv2_generic_rw_locked().

media: anysee: accept read buffers of length 1 in anysee_master_xfer

2024-04-08T11:48:18Z

anysee_master_xfer currently accepts read messages of length 2 only. However, several frontends, e.g. tda10023 send buffers of length 1, containing an 8-bit register number (see tda10023_readreg). These buffers are rejected currently, making many Anysee variants to not work. In these cases the "Unsupported Anysee version" message is logged. This patch alters the function to accept buffers of a length of 1 too. Signed-off-by: István Váradi Signed-off-by: Hans Verkuil [hverkuil: add spaces around '<', fix typo in 'sevaral']
