Runtime power management support breaks Intel LTE modem where dmesg dump showes timeout errors: ``` [ 72.027442] iosm 0000:01:00.0: msg timeout [ 72.531638] iosm 0000:01:00.0: msg timeout [ 73.035414] iosm 0000:01:00.0: msg timeout [ 73.540359] iosm 0000:01:00.0: msg timeout ``` Furthermore, when shutting down with `poweroff` and modem attached, the system rebooted instead of powering down as expected. The modem works again only after power cycling. Revert runtime power management support for IOSM driver as introduced by commite4f5073d53("net: wwan: iosm: enable runtime pm support for 7560").

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.
