lutX should not be used

[Insomnia1437]

When mapping EVR output to Prescaler 1, OPI reported READ_ALARM. real output is not affected

It looks like the info field of lutX should be reserved as an "unknown" option.

I am looking into it and will fix it when I have time

@Insomnia1437 , as far I can notice quickly, mrfioc2/mrfCommon/src/devlutstring.cpp Lines 90 to 96 in 5b0c1a1 can be deleted. It looks like an artifact, what is the purpose of that?

info(lutX, ...) was intended to allow the default "unknown" string to be customized. Of course such customization is not a requirement.

https://github.com/epics-modules/mrfioc2/blob/5b0c1a1739a210ffc8bfe1b1118723cdd9fd6ee2/mrfCommon/src/devlutstring.cpp#L80

This being the default string when no entry matches

As Michael explained, I think it's more appropriate to keep this customization. I suggest changing the hard-coded lutX to lutXX to increase future scalability.

Ok, so I propose PR https://github.com/epics-modules/mrfioc2/pull/175 with lutX changed to lut_ to avoid the letters.
