[ Upstream commit 4dc4e22f9536341255f5de6047977a80ff47eaef ]
Since commit 4ff6039ffb79 ("coresight-etm4x: add isb() before reading
the TRCSTATR"), the code has incorrectly been polling the PMSTABLE bit
instead of the IDLE bit.
This commit corrects the typo.
Fixes: 4ff6039ffb79 ("coresight-etm4x: add isb() before reading the TRCSTATR")

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.
