commit544e737deaupstream. Commit2aa36604e8("PM: sleep: Avoid calling put_device() under dpm_list_mtx") forgot to update the while () loop termination condition to also break the loop if error is nonzero, which causes the loop to become infinite if device_prepare() returns an error for one device. Add the missing !error check. Fixes:2aa36604e8("PM: sleep: Avoid calling put_device() under dpm_list_mtx") Signed-off-by: Rafael J.

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.
