[ Upstream commit 3cfdf8fcaafa62a4123f92eb0f4a72650da3a479 ]

When cmtp_attach_device fails, cmtp_add_connection returns the error value
which leads to the caller to doing fput through sockfd_put. But
cmtp_session kthread, which is stopped in this path will also call fput,
leading to a potential refcount underflow or a use-after-free.

Add a refcount before we signal the kthread to stop. The kthread will try
to grab the cmtp_session_sem mutex before doing the fput, which is held
when get_file is called, so there should be no races there.

0x2B, 0x31 and 0x33 are reserved for future use but were not present in
the HCI to MGMT conversion table, this caused the conversion to be
incorrect for the HCI status code greater than 0x2A.

[ Upstream commit 06d213d8a89a6f55b708422c3dda2b22add10748 ]

For incoming SCO connection with transparent coding format, alt setting
of CVSD is getting applied instead of Transparent.

So move the shutdown callback to a place where workqueues are either
flushed or cancelled to resolve the issue.

[ Upstream commit 0324d19cb99804d99e42c990b8b1e191575a091b ]

This patch adds the 0cf3:e500 Bluetooth device (from a QCA9377 board) as a
QCA_ROME device.  It appears to be functionally identical to another device
ID, also from a QCA9377 board, which was previously marked as QCA_ROME in
0a03f98b98c201191e3ba15a0e33f46d8660e1fd
("Bluetooth: Add a new 04ca:3015 QCA_ROME device").

Without this patch, the WiFi side of the QCA9377 board is slow or unusable
when the Bluetooth side is in use.

See https://askubuntu.com/a/1137852 for another report of QCA_ROME fixing
this issue for this device ID.

Because mSBC frames do not need to be aligned to the SCO packet
boundary. Using USB ALT 3 let HCI payload >= 60 bytes, let mSBC
data satisfy 60 Bytes avoid payload unaligned situation and fixed
some headset no voise issue.

USB Alt 3 supported also need HFP support transparent MTU in 72 Bytes.

This is btsoc timing issue, after host start to downloading bt firmware,
ep2 need time to switch from function acl to function dfu, so host add
20ms delay as workaround.
