From: Matt Roper Date: Tue, 18 Feb 2025 20:05:12 +0000 (-0800) Subject: drm/xe: Drop unnecessary GT lookup in xe_exec_queue_create_ioctl() X-Git-Tag: v6.15-rc1~120^2~15^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a1e5b6d83e03d60d15ba393cbbd7d5c13e5cf0b3;p=thirdparty%2Fkernel%2Flinux.git drm/xe: Drop unnecessary GT lookup in xe_exec_queue_create_ioctl() xe_exec_queue_create_ioctl() performs a lookup of the xe_gt for the GT ID passed from userspace, but the result is never actually used. Since there's already a separate (and earlier) check that the ID passed from userspace is valid, the unnecessary lookup can be removed.
