When the SD host controller tries to probe again due to the derferred
probe mechanism, it will always keep the SD host device as runtime
resume state due to missing the runtime put operation in error path
last time.
Thus add the pm_runtime_put_noidle() in error path to make the PM runtime
counter balance, which can make the SD host device's PM runtime work well.

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.
