Explicitly cast xemaclite_readl return value when it's passed to ntohl. Fixes below reported sparse warnings: xilinx_emaclite.c:411:24: sparse: sparse: cast to restricted __be32 xilinx_emaclite.c:420:36: sparse: sparse: cast to restricted __be32 Signed-off-by: Radhey Shyam Pandey <redacted> Reported-by: kbuild test robot <redacted> --- drivers/net/ethernet/xilinx/xilinx_emaclite.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
