Subject: your recently submitted patch to fix BT RIP error shall be applied to
 6.6 stable (I have a systematic crash on reboot in 6.6.23)

hci_cmd_sync_cancel_sync shall check the error passed to it since it
will be propagated using req_result which is __u32 it needs to be
properly set to a positive value if it was passed as negative othertise
IS_ERR will not trigger as -(errno) would be converted to a positive
value.

On my MSI laptop, on coldboot I have no bt errors but when I restart I 
alway get qeveral (firmware download error, ...). Without your proposed 
patch, I get a systematic RIP when rebooting, and after the laptop does 
not properly shutdown.

Your patch applies with offsets.
