kmsg_dump: fix build for CONFIG_PRINTK=n
kmsg_dump() fails to build when CONFIG_PRINTK=n; provide stubs for the kmsg_dump*() functions when CONFIG_PRINTK=n. kernel/printk.c: In function 'kmsg_dump': kernel/printk.c:1501: error: 'log_buf_len' undeclared (first use in this function) kernel/printk.c:1502: error: 'logged_chars' undeclared (first use in this function) kernel/printk.c:1506: error: 'log_buf' undeclared (first use in this function) Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Acked-by: Simon Kagstrom <simon.kagstrom@netinsight.net> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
