From a2a5f1a2d23b453e2f11c10928c54b282fbe6147 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 9 May 2016 09:11:54 +0200 Subject: net: ircomm, cleanup TIOCGSERIAL In ircomm_tty_get_serial_info, struct serial_struct is memset to 0 and then some members set to 0 explicitly. Remove the latter as it is obviously superfluous. And remove the retinfo check against NULL. copy_to_user will take care of that. Part of hub6 cleanup series.
