Alex Elder 7906a075c9 remoteproc: Fix IDR initialisation in rproc_alloc()
[ Upstream commit 6442df49400b466431979e7634849a464a5f1861 ]

If ida_simple_get() returns an error when called in rproc_alloc(),
put_device() is called to clean things up.  By this time the rproc
device type has been assigned, with rproc_type_release() as the
release function.

The first thing rproc_type_release() does is call:
    idr_destroy(&rproc->notifyids);

But at the time the ida_simple_get() call is made, the notifyids
field in the remoteproc structure has not been initialized.

I'm not actually sure this case causes an observable problem, but
it's incorrect.  Fix this by initializing the notifyids field before
calling ida_simple_get() in rproc_alloc().

Fixes: b5ab5e24e9 ("remoteproc: maintain a generic child device for each rproc")

README

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.
