The dc_data structure holds data required for handling compression
operations, such as overflow buffers. In this context, the use of

is not necessary, as these data structures are freed and

3a1edef8f4b58b0ba826bc68bf4bce4bdf59ecf3 | Analyze and fix the following issue in the Linux kernel code: drm/xe: Make WA BB part of LRC BO | Problem Details:
No idea why, but without this GuC context switches randomly fail when
running IGTs in a loop. Need to follow up why this fixes the
aforementioned issue but can live with a stable driver for now.
Fixes: 617d824c5323 ("drm/xe: Add WA BB to capture active context utilization")
