Tomonori Sakita c91f641625 net: altera_tse: fix msgdma_tx_completion on non-zero fill_level case ... [ Upstream commit 6571ebce112a21ec9be68ef2f53b96fcd41fd81b ] If fill_level was not zero and status was not BUSY, result of "tx_prod - tx_cons - inuse" might be zero. Subtracting 1 unconditionally results invalid negative return value on this case. Make sure not to return an negative value.
