net: dpaa_eth: print FD status in CPU endianness in dpaa_eth_fd tracepoint
[ Upstream commit 0144c06c5890d1ad0eea65df074cffaf4eea5a3c ]
Sparse warns:
note: in included file (through ../include/trace/trace_events.h,
../include/trace/define_trace.h,
../drivers/net/ethernet/freescale/dpaa/dpaa_eth_trace.h):
warning: incorrect type in assignment (different base types)
expected unsigned int [usertype] fd_status
got restricted __be32 const [usertype] status
We take struct qm_fd :: status, store it and print it as an u32,
though it is a big endian field. We should print the FD status in
CPU endianness for ease of debug and consistency between PowerPC and
Arm systems.
Though it is a not often used debug feature, it is best to treat it as
a bug and backport the format change to all supported stable kernels,
for consistency.
