[PATCH] pcmcia: cleanup cs.c, reduce size
kill the socket_shutdown()/shutdown_socket() confusion by making it one single function. move cs_socket_put() in there. nicer to read and smaller: original: text data bss dec hex filename 25181 1076 32 26289 66b1 drivers/pcmcia/pcmcia_core.ko patched: text data bss dec hex filename 24973 1076 32 26081 65e1 drivers/pcmcia/pcmcia_core.ko Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
