Subject[PATCH 08/11] uml console channels: remove console_write wrappers
Date
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

We were using a long series of (stupid) wrappers which all call
generic_console_write(). Since the wrappers only change the 4th param, which is
unused by the called proc, remove them and call generic_console_write()
directly.

If needed at any time in the future to reintroduce this stuff, the member could
be moved to a generic struct, to avoid this duplicated handling.
