From 6576c2891adacad81ea0b24f0704ecac9fc727cb Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 8 Feb 2010 10:12:32 +0000 Subject: CAPI: Drop obsolete nccip from capiminor struct The nccip in capiminor used to serve as an indicator that the NCCI was close. But we don't need this, we issue a hangup on capincci_free_minor. So drop this legacy. Signed-off-by: Jan Kiszka Signed-off-by: David S.
