Subject: [PATCH v2 8/9] isdn: Remove unused variable causing a compile build

Thanks for reviewing Paul. Here's the result:

Author: Lee Jones <>
Date:   Sat Nov 3 22:06:02 2012 +0100

    isdn: Encapsulate variable 's' in same CONFIG_NETDEVICES guards as code using it
    In the current case, variable 's' of type 'char *' is defined but then
    not used if !CONFIG_NETDEVICES, casing the compile-time warning below.
    In this change we surround the declaration using the same guards as
    the pre-processed code which makes use of it.
    This patch fixes:
    drivers/isdn/i4l/isdn_common.c: In function ‘isdn_ioctl’:
    drivers/isdn/i4l/isdn_common.c:1278:8: warning: unused variable ‘s’ [-Wunused-variable]
