[PATCH v4 03/24] drm/i915: Setup less PPGTT on failed page_directory

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ben Widawsky <benjamin.widawsky@xxxxxxxxx>

The current code will both potentially print a WARN, and setup part of
the PPGTT structure. Neither of these harm the current code, it is
simply for clarity, and to perhaps prevent later bugs, or weird
debug messages.
