Fix the following checkpatch warnings. WARNING: debugfs_remove_recursive(NULL) is safe this check is probably not required WARNING: min() should probably be min_t(u32, rx_left, dw_readw(dws, DW_SPI_RXFLR)) WARNING: else is not generally useful after a break or return WARNING: Missing a blank line after declarations WARNING: void function return statements are not generally useful
