[PATCH] [net] dibs: Improve DIBS prompts and help texts

[PATCH] [net] dibs: Improve DIBS prompts and help texts

[Geert Uytterhoeven]

The Kconfig prompts for the DIBS options read:

    DIBS support (DIBS) [N/m/y/?]
      intra-OS shortcut with dibs loopback (DIBS_LO) [N/y/?]

Clarify the DIBS prompt by expanding the acronym.
Capitalize the first character of the DIBS_LO prompt, and always write
DIBS in full caps.
While at it, join the first two lines of the DIBS help text into a real
sentence.

Thank you, yes that is an improvement.

dibs is a shim layer between other kernel components and code pieces are
typically lowercase, same for sysfs paths. It is not some formal standard
that is documented anywhere in uppercase. So I'd like to keep it lowercase
in the help text.

I could consider changing this to (dibs), if people think that is easier to read.
But I thought it more obvious this way.

The module name is definitively dibs in lowercase.

My fault, that is indeed a silly mistake.
Will send v2 later, taking your comments into accoun.
