Message-ID: <20100523-patch-gigaset-02.tilman@imap.cc> Date: Sun, 23 May 2010 13:02:38 +0200 (CEST) From: Tilman Schmidt <tilman@...p.cc> To: Karsten Keil <isdn@...ux-pingi.de>, David Miller <davem@...emloft.net> CC: Hansjoerg Lipp <hjlipp@....de>, Karsten Keil <keil@...systems.de>, i4ldeveloper@...tserv.isdn4linux.de, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] 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.
