SKL DDI B/C/D only have 9 usable buf trans registers for DP/eDP. That matches the normal DP buf trans tables, but the low vswing eDP tables have 10 entries. Thus the eDP tables can only be used safely with DDI A and E. We try to catch cases where DDI B/C/D gets used with the wrong number of entires in some parts of the code, but not everywhere. Let's move the code to deal with that deeper into intel_ddi_get_buf_trans_edp(). And for sake of symmetry do the same in intel_ddi_get_buf_trans_dp(). That would also avoid explosions in the rather unlikely case that the DP tables would get revised to 10 entries as well.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
