5f60d5f6bb move asm/unaligned.h to linux/unaligned.h
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.

f0c83a23fc Bluetooth: btmtk: Fix btmtk.c undefined reference build error
MediaTek moved some usb interface related function to btmtk.c which

d09009bc80 Bluetooth: btmtk: Fix kernel crash when entering btmtk_usb_suspend
If MediaTek's Bluetooth setup is unsuccessful, a NULL pointer issue
occur when the system is suspended and the anchored kill function
is called. To avoid this, add protection to prevent executing the
anchored kill function if the setup is unsuccessful.

ceac1cb025 Bluetooth: btusb: mediatek: add ISO data transmission functions
This patch implements functions for ISO data send and receive in btusb
driver for MediaTek's controller.

MediaTek defines a specific interrupt endpoint for ISO data transmissin
because the characteristics of interrupt endpoint are similar to the
application of ISO data which can support guaranteed transmissin
bandwidth, enough maximum data length and error checking mechanism.

Driver sets up ISO interface and endpoints in btusb_mtk_setup and clears
the setup in btusb_mtk_shutdown. These flow can't move to btmtk.c due to
btusb_driver is only defined in btusb.c when claiming/relaesing interface.
ISO packet anchor stops when driver suspending and resubmit interrupt urb
for ISO data when driver resuming.

3e465a07cd Bluetooth: btmtk: Add MODULE_FIRMWARE() for MT7922
Since dracut refers to the module info for defining the required
firmware files and btmtk driver doesn't provide the firmware info for
MT7922, the generate initrd misses the firmware, resulting in the
broken Bluetooth.

This patch simply adds the MODULE_FIRMWARE() for the missing entry
for covering that.

This patch implement function .coredump() and dmp_hdr() in btusb

specific event to show something unexpected happened in the controller.

The driver would be responsible for collecting and uploading the device
core dump pieces in hci driver using core dump API. Once we finished
the whole process, the driver would reset the controller to recover the
kind of fatal error.
