From: Shiwu Zhang <[email protected]> For gfx_v9_4_3 and beyond, struct kiq has its own mqd_backup pointer rather than using the last pointer from mec struct. Then the kfree operation on the pointer from the mec struct should be removed otherwise it will cause double free on the first kcq's mqd_backup buffer on XCD1.
