[PATCH 0/3] More strict input value validation

[Ken ICHIKAWA]

Now, ptp4l and phc2sys accept obviously invalid arg values.
For example of logging level:
-l abcd
-l 6a
-l -1
-l 8
These values are accepted.

This patchset provides more strict arg value validation for ptp4l and
phc2sys.

Ken ICHIKAWA (3):
Add functions for input error checking
ptp4l: provide more strict arg value check
phc2sys: provide more strict arg value check
