Andrzej Hajda 84a6e47545 drm/i915: do not clean GT table on error path [ Upstream commit `0561794b6b` ] The only task of intel_gt_release_all is to zero gt table. Calling it on error path prevents intel_gt_driver_late_release_all (called from i915_driver_late_release) to cleanup GTs, causing leakage. After i915_driver_late_release GT array is not used anymore so it does not need cleaning at all. Sample leak report: BUG i915_request (...): Objects remaining in i915_request on __kmem_cache_shutdown() ...

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.
