[PATCH openEuler-22.03-LTS-SP1] dma: fix call order in dmam_free_coherent

From: Lance Richardson <rlance(a)google.com> stable inclusion from stable-v6.6.44 commit 1fe97f68fce1ba24bf823bfb0eb0956003473130 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKQ2W CVE: CVE-2024-43856 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 28e8b7406d3a1f5329a03aa25a43aa28e087cb20 ] dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for reuse, then calls devres_destroy() to remove and free the data structure used to track the DMA allocation. Between the two calls, it is possible for a concurrent task to make an allocation with the same vaddr and add it to the devres list. If this happens, there will be two entries in the devres list with the same vaddr and devres_destroy() can free the wrong entry, triggering the WARN_ON() in dmam_match. Fix by destroying the devres entry before freeing the DMA allocation.
