From 7f971dfd48983074adc7bbcea3ee95ce7aad47cb Mon Sep 17 00:00:00 2001 From: Shuicheng Lin Date: Wed, 25 Feb 2026 01:34:49 +0000 Subject: drm/xe/configfs: Free ctx_restore_mid_bb in release [ Upstream commit e377182f0266f46f02d01838e6bde67b9dac0d66 ] ctx_restore_mid_bb memory is allocated in wa_bb_store(), but xe_config_device_release() only frees ctx_restore_post_bb. Free ctx_restore_mid_bb[0].cs as well to avoid leaking the allocation when the configfs device is removed.
