Clark Wang 3d3a2307ff i3c: master: svc: fix cpu schedule in spin lock
[ Upstream commit 33beadb3b1 ]

pm_runtime_resume_and_get() may call sleep(). It cannot be used in
svc_i3c_master_start_xfer_locked(), because it is in a spin lock.

Move the pm runtime operations to svc_i3c_master_enqueue_xfer().

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.
