Frank Li 66db99ffdf perf/imx_ddr: Move ida_alloc() from ddr_perf_init() to ddr_perf_probe()
Move ida_alloc() from helper ddr_perf_init() into ddr_perf_probe() to
clarify why ida_free() must be called at the error path.

Add return value check for ida_alloc().

Rename label 'cpuhp_state_err' to 'idr_free' to make the code clearer,
since two error paths now jump to this label.

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 reStructuredText 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.
