[PATCH] Char: mxser_new, kill unneeded memsets
mxser_new, kill unneeded memsets There is no need to re-zero static global variables' memory, hence memsets doing this are useless. alloc_tty_struct also zeroes allocated memory: another candidate for removing. This fixes also a bug -- global structures are cleaned up after initialization of some its parts.
