[ Upstream commit 0fd181456aa0826057adbfb6c79c40f4083cfd75 ] BRM_status_show() has several error branches, but none of them record the error in the error return. Also while at it remove the manual mutex_unlock() of the pci_access_mutex in case of an ongoing pci error recovery or host removal and jump to the cleanup label instead. Note: We can safely jump to out from here as io_unit_pg3 is initialized to NULL and if it hasn't been allocated, kfree() skips the NULL pointer.

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.
