[PATCH v2 4/6] i2cset: Ensure that there is no junk after the command/mode parameter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since the value mask can no longer be set after the mode command,
we can make sure that there is no junk after the command/mode
parameter in the command line.
