From 3c76c58fca03c1162ab8592f71c996e933af3a9e Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 17 Apr 2011 16:35:27 -0700 Subject: isdn: hfcsusb: Fix set-but-unused variables. The variable 'buf' is set but unused in ctrl_complete(). Just kill it off. Similarly for the variable 'err' in setup_hfcsusb(). Signed-off-by: David S.
