You probably want to use i2c_smbus_write_i2c_block_data instead. With
i2c_smbus_write_block_data, the first data byte isn't real data,
instead in indicates how many bytes follow until the end of the block.
It should result in "5D W 11 33 44" in your case though, not sure why
you get "5D W 11 03 33" instead.
