Subject: [PATCH 1/4] Char: mxser_new, kill unneeded memsets
Date: Sun, 1 Oct 2006 00:33:38 +0200 (CEST) [thread overview]
Message-ID: <81721356982173@wsc.cz> (raw)
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.
