Subject: [PATCH] Revert "drm/i915/gem: Allow EXEC_CAPTURE on recoverable
 contexts on DG1"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

This reverts commit d6e020819612a4a06207af858e0978be4d3e3140.

The IS_DGFX check was put in place because error capture of buffer
objects is expected to be broken on devices with VRAM.

Userspace fix[1] to the impacted media driver has been submitted, merged
and a new driver release is out as 25.2.3 where the capture flag is
dropped on DG1 thus unblocking the usage of media driver on DG1.
