Imre Deak 3a86cb16ab drm/i915: Prevent HW access during init from connector get_modes hooks Prevent accessing the HW from the get_modes hooks of connectors deriving the mode list from the display's EDID. drm_edid_connector_add_modes() will return the mode list based on the EDID which was cached during a previous detection/get_modes call. This also fixes the NULL deref problem (10085) which was introduced/revealed by commit `bab87ef4db` ("drm/i915: Disable hotplug detection handlers during driver init/shutdown") After the above change MST connectors will not change state during driver init/shutdown; thus some of these connectors with no I2C/DDC adapter registered for them (since the given MST port has no sink connected) may stay then in the 'unknown' connector status. The get_modes() hook should not try to use the I2C/DDC adapter in this state (which would lead to the above NULL deref) which this patch ensures. v2: - Remove the redundant check from intel_crt_ddc_get_modes(). - Rebase on latest drm-tip. - Add Fixes: line / related commit notes.

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.
