commit 1fdc4dca350c0b8ada0b8ebf212504e1ad55e511 upstream.
wdm_wwan_port_tx_complete is called from a completion
handler with irqs disabled and possible in IRQ context
usb_autopm_put_interface can take a mutex.
Hence usb_autopm_put_interface_async must be used.
Fixes: cac6fb015f ("usb: class: cdc-wdm: WWAN framework integration")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
