[Why & How] Due to some code flow constraints, we need to defer dc_lock needed works from dc_link_handle_hpd_rx_irq(). Thus, do following changes: * Change allow_hpd_rx_irq() from static to public * Change handle_automated_test() from static to public * Extract link lost handling flow out from dc_link_handle_hpd_rx_irq() and put those into a new function dc_link_dp_handle_link_loss() * Add one option parameter to decide whether defer works within dc_link_handle_hpd_rx_irq() Acked-by: Mikita Lipski <mikita.lipski@amd.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
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.
