------------------------------------------------------
Subject: isdn: guard against a potential NULL pointer dereference in old_capi_manufacturer()
From: Jesper Juhl <jesper.juhl@xxxxxxxxx>
In drivers/isdn/capi/kcapi.c::old_capi_manufacturer(), if the call to
get_capi_ctr_by_nr(ldef.contr); in line 823 returns NULL, then we'll be
dereferencing a NULL pointer in the very next line.
(Found by Coverity checker as bug #402)
