From e487639dc8ca6bd6c19a4140f45ebc88da56ddd5 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Sun, 23 May 2010 01:02:38 +0000 Subject: isdn/gigaset: remove dummy CAPI method implementations Dummy implementations for the optional CAPI controller operations load_firmware and reset_ctr can cause userspace callers to hang indefinitely. It's better not to implement them at all. Signed-off-by: Tilman Schmidt Acked-by: Karsten Keil Signed-off-by: David S.
