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

Bluetooth: btintel: Remove unneeded CONFIG_PM* #ifdef's

2026-01-29T18:34:47+00:00

The functions are already disabled if CONFIG_PM or CONFIG_PM_SLEEP are disabled through the use of SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS(). This increases build coverage and allows to drop a few #ifdef's. Signed-off-by: Bastien Nocera Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Remove redundant pm_runtime_mark_last_busy() calls

2025-12-01T21:00:07+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy(). Signed-off-by: Sakari Ailus Signed-off-by: Luiz Augusto von Dentz

Bluetooth: fix corruption in h4_recv_buf() after cleanup

2025-10-24T14:31:24+00:00

A different structure is stored in drvdata for the drivers which used that duplicate function, but h4_recv_buf() assumes drvdata is always an hci_uart structure. Consequently, alignment and padding are now randomly corrupted for btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic breakage. Fix this by making the hci_uart structure the explicit argument to h4_recv_buf(). Every caller already has a reference to hci_uart, and already obtains the hci_hdev reference through it, so this actually eliminates a redundant pointer indirection for all existing callers.

Bluetooth: hci_dev: replace 'quirks' integer by 'quirk_flags' bitmap

2025-07-16T19:37:53+00:00

The 'quirks' member already ran out of bits on some platforms some time ago. Replace the integer member by a bitmap in order to have enough bits in future. Replace raw bit operations by accessor macros.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

Bluetooth: hci_intel: Convert to platform remove callback returning void

2024-05-14T14:51:03+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Luiz Augusto von Dentz
