If there is no interconnect-names, but there is an interconnects property, then of_icc_get(dev, "gfx-mem"); would return an error rather than NULL. Also, if there is no interconnect-names property, there will never be a ocmem path. But of_icc_get(dev, "ocmem") would return -EINVAL instead of -ENODATA. Just don't bother trying in this case. v2: explicity check for interconnect-names property Fixes:08af4769c7("drm/msm: handle for EPROBE_DEFER for of_icc_get") Fixes:00bb9243d3("drm/msm/gpu: add support for ocmem interconnect path") Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
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.
