Posting them as a standalone series because the QCC2072 driver itself is larger and will take longer to review. These prerequisites are small and self-contained, so they can hopefully be reviewed and merged on their own in the meantime. Signed-off-by: Zijun Hu --- Changes in v2: - btusb: drop "Build the driver from multiple source files"; the split into btusb_main.c needs more discussion and will be sent separately - coredump: implement hci_devcd_state_name() with a switch returning "Unknown" for out-of-range states, instead of an array lookup - btusb: make btusb_recv_{event,acl}() take struct hci_dev * directly, instead of adding separate btusb_recv_{event,acl}_hdev() wrappers - Link to v1: https://lore.kernel.org/r/20260708-btusb_prep_qcc2072-v1-0-d835b187fd01@oss.qualcomm.com --- Zijun Hu (5): Bluetooth: coredump: Introduce and apply hci_devcd_state_name() Bluetooth: coredump: Allow drivers to pad dump header to fixed size Bluetooth: btusb: Add an indirect recv_intr() hook to btusb_data Bluetooth: btusb: Make btusb_recv_{event,acl}() take struct hci_dev * Bluetooth: btusb: Add a simple static btusb_prepare_reset() drivers/bluetooth/btusb.c | 33 +++++++++++++++++-------- include/net/bluetooth/coredump.h | 11 +++++++++ net/bluetooth/coredump.c | 52 ++++++++++++++++++++++++++++++---------- 3 files changed, 74 insertions(+), 22 deletions(-) --- base-commit: eab19cb7618e5c50fd1f8c1efdc4e66e16575975 change-id: 20260708-btusb_prep_qcc2072-23604a4e81d1 Best regards, -- Zijun Hu
