CVE-2022-50384

In the Linux kernel, the following vulnerability has been resolved: staging: vme_user: Fix possible UAF in tsi148_dma_list_add Smatch report warning as follows: drivers/staging/vme_user/vme_tsi148.c:1757 tsi148_dma_list_add() warn: '&entry->list' not removed from list In tsi148_dma_list_add(), the error path "goto err_dma" will not remove entry->list from list->entries, but entry will be freed, then list traversal may cause UAF. Fix by removeing it from list->entries before free().
