Bluetooth: btbcm: Add entry for BCM4343A2 UART Bluetooth

2026-04-10T14:22:21+00:00

This patch adds the device ID for the BCM4343A2 module, found e.g. in the muRata 1YN WiFi+BT combined device. The required firmware file is named 'BCM4343A2.hcd'. Signed-off-by: Marek Vasut Reviewed-by: Paul Menzel Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btbcm: remove done label in btbcm_patchram

2026-04-10T14:20:22+00:00

There is no point in having the label since all it does is return the value in the 'err' variable. Instead make every goto return directly and remove the label. Signed-off-by: Dongyang Jin Reviewed-by: Paul Menzel Signed-off-by: Luiz Augusto von Dentz

drivers/bluetooth: btbcm: Use kmalloc_array() to prevent overflow

2025-12-01T21:21:16+00:00

Replace the open-coded multiplication in kmalloc() with a call to kmalloc_array() to prevent potential integer overflows. This is a mechanical change, replacing BCM_FW_NAME_LEN with the type-safe sizeof(*fw_name) as the element size Signed-off-by: Ayaan Mirza Baig Signed-off-by: Luiz Augusto von Dentz

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.

Bluetooth: btbcm: Fix NULL deref in btbcm_get_board_name()

2025-01-15T15:34:27+00:00

devm_kstrdup() can return a NULL pointer on failure,but this returned value in btbcm_get_board_name() is not checked. Add NULL check in btbcm_get_board_name(), to handle kernel NULL pointer dereference error.

Bluetooth: btbcm: fix missing of_node_put() in btbcm_get_board_name()

2024-11-14T20:35:40+00:00

of_find_node_by_path() returns a pointer to a device_node with its refcount incremented, and a call to of_node_put() is required to decrement the refcount again and avoid leaking the resource. If 'of_property_read_string_index(root, "compatible", 0, &tmp)' fails, the function returns without calling of_node_put(root) before doing so. The automatic cleanup attribute can be used by means of the __free() macro to automatically call of_node_put() when the variable goes out of scope, fixing the issue and also accounting for new error paths.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Bluetooth: btbcm: Use devm_kstrdup()

Bluetooth: btbcm: add default address for BCM43430A1

2023-08-11T18:50:05+00:00

The BCM43430A1 has a default MAC address of AA:AA:AA:AA:AA:AA. Although, unlike some other entries, this does not include the chip name, it is clearly not a real address. This was found in AzureWave AW-NB197SM and AW-NM372SM modules. Signed-off-by: Mans Rullgard Signed-off-by: Luiz Augusto von Dentz
