4.19-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit 388a49959ee4e4e99f160241d9599efa62cd4299 ] In qla2x00_async_tm_cmd, we reference off sp after it has been freed. This caused a panic on a system running a slub debug kernel. Since fcport is passed in anyways, just use that instead.
