a=openpgp; fpr=2437CB76E544CB6AB3D9DFD399739260CB6CB716 Several recent patches added static stubs to btmtk.h without the inline keyword, which causes instances of -Wunused-function when those stubs are not used anywhere in a file that includes the header: In file included from drivers/bluetooth/btusb.c:28: drivers/bluetooth/btmtk.h:254:13: warning: 'btmtk_fw_get_filename' defined but not used [-Wunused-function] 254 | static void btmtk_fw_get_filename(char *buf, size_t size, u32 dev_id, | ^~~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtk.h:249:12: warning: 'btmtk_process_coredump' defined but not used [-Wunused-function] 249 | static int btmtk_process_coredump(struct hci_dev *hdev, struct sk_buff *skb) | ^~~~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtk.h:243:12: warning: 'btmtk_register_coredump' defined but not used [-Wunused-function] 243 | static int btmtk_register_coredump(struct hci_dev *hdev, const char *name, | ^~~~~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtk.h:233:12: warning: 'btmtk_setup_firmware' defined but not used [-Wunused-function] 233 | static int btmtk_setup_firmware(struct hci_dev *hdev, const char *fwname, | ^~~~~~~~~~~~~~~~~~~~ drivers/bluetooth/btmtk.h:227:12: warning: 'btmtk_setup_firmware_79xx' defined but not used [-Wunused-function] 227 | static int btmtk_setup_firmware_79xx(struct hci_dev *hdev, const char *fwname, | ^~~~~~~~~~~~~~~~~~~~~~~~~ Add inline to all the stubs in btmtk.h (even ones that do not currently have any warnings associated with them) to ensure there are never unused function warnings from these stubs, as is customary for the kernel. Signed-off-by: Nathan Chancellor --- I omitted a fixes tag because it seems like this was done over several changes and I think breaking this up is not really necessary but I am happy to do so if so desired. --- drivers/bluetooth/btmtk.h | 39 +++++++++++++++++++++------------------ 1 file changed, 21 insertions(+), 18 deletions(-) --- base-commit: c60d1a6e1dae1623169d0d97bfd3e50003072eae change-id: 20240710-btmtk-add-missing-inline-to-stubs-f3636bcda67e Best regards, diff --git a/drivers/bluetooth/btmtk.h b/drivers/bluetooth/btmtk.h index 453ed5131a37..5df7c3296624 100644 --- a/drivers/bluetooth/btmtk.h +++ b/drivers/bluetooth/btmtk.h @@ -224,70 +224,73 @@ static inline int btmtk_set_bdaddr(struct hci_dev *hdev, return -EOPNOTSUPP; } -static int btmtk_setup_firmware_79xx(struct hci_dev *hdev, const char *fwname, - wmt_cmd_sync_func_t wmt_cmd_sync) +static inline int btmtk_setup_firmware_79xx(struct hci_dev *hdev, + const char *fwname, + wmt_cmd_sync_func_t wmt_cmd_sync) { return -EOPNOTSUPP; } -static int btmtk_setup_firmware(struct hci_dev *hdev, const char *fwname, - wmt_cmd_sync_func_t wmt_cmd_sync) +static inline int btmtk_setup_firmware(struct hci_dev *hdev, const char *fwname, + wmt_cmd_sync_func_t wmt_cmd_sync) { return -EOPNOTSUPP; } -static void btmtk_reset_sync(struct hci_dev *hdev) +static inline void btmtk_reset_sync(struct hci_dev *hdev) { } -static int btmtk_register_coredump(struct hci_dev *hdev, const char *name, - u32 fw_version) +static inline int btmtk_register_coredump(struct hci_dev *hdev, + const char *name, u32 fw_version) { return -EOPNOTSUPP; } -static int btmtk_process_coredump(struct hci_dev *hdev, struct sk_buff *skb) +static inline int btmtk_process_coredump(struct hci_dev *hdev, + struct sk_buff *skb) { return -EOPNOTSUPP; } -static void btmtk_fw_get_filename(char *buf, size_t size, u32 dev_id, - u32 fw_ver, u32 fw_flavor) +static inline void btmtk_fw_get_filename(char *buf, size_t size, u32 dev_id, + u32 fw_ver, u32 fw_flavor) { } -static int btmtk_usb_subsys_reset(struct hci_dev *hdev, u32 dev_id) +static inline int btmtk_usb_subsys_reset(struct hci_dev *hdev, u32 dev_id) { return -EOPNOTSUPP; } -static int btmtk_usb_recv_acl(struct hci_dev *hdev, struct sk_buff *skb) +static inline int btmtk_usb_recv_acl(struct hci_dev *hdev, struct sk_buff *skb) { return -EOPNOTSUPP; } -static struct urb *alloc_mtk_intr_urb(struct hci_dev *hdev, struct sk_buff *skb, - usb_complete_t tx_complete) +static inline struct urb *alloc_mtk_intr_urb(struct hci_dev *hdev, + struct sk_buff *skb, + usb_complete_t tx_complete) { return ERR_PTR(-EOPNOTSUPP); } -static int btmtk_usb_resume(struct hci_dev *hdev) +static inline int btmtk_usb_resume(struct hci_dev *hdev) { return -EOPNOTSUPP; } -static int btmtk_usb_suspend(struct hci_dev *hdev) +static inline int btmtk_usb_suspend(struct hci_dev *hdev) { return -EOPNOTSUPP; } -static int btmtk_usb_setup(struct hci_dev *hdev) +static inline int btmtk_usb_setup(struct hci_dev *hdev) { return -EOPNOTSUPP; } -static int btmtk_usb_shutdown(struct hci_dev *hdev) +static inline int btmtk_usb_shutdown(struct hci_dev *hdev) { return -EOPNOTSUPP; }
