[PATCH 4.19 18/36] cxgb4: fix SGE queue dump destination buffer context
From: Greg Kroah-Hartman
Date: Tue Jul 07 2020 - 11:18:46 EST
From: Rahul Lakkireddy <rahul.lakkireddy@xxxxxxxxxxx>
[ Upstream commit 1992ded5d111997877a9a25205976d8d03c46814 ]
The data in destination buffer is expected to be be parsed in big
endian. So, use the right context.
Fixes following sparse warning:
cudbg_lib.c:2041:44: warning: incorrect type in assignment (different
base types)
cudbg_lib.c:2041:44: expected unsigned long long [usertype]
cudbg_lib.c:2041:44: got restricted __be64 [usertype]
Fixes: 736c3b94474e ("cxgb4: collect egress and ingress SGE queue contexts")
