This series of patches renames the N_AMSDELTA line discipline, used by the Amstrad Delta ASoC machine driver and the CX20442 ASoC codec driver for controlling the CX20442 voice codec over the CX81801 voice modem, giving it a more generic name: N_V253. The name has been chosen after the voice modem standard codename V.253. I think that even if the code of the line discipline is currently implemented inside those two specific drivers, the idea, if not the code, could be reused with other similar hardware configurations, if necessary. As the line discipline is conceived to be registered from a machine driver, there should be no conflicts, even if used by several different drivers that happen to be be built-in side-by-side.
