From 07261edb971492c6b41b44d7b1b51f76807d30ad Mon Sep 17 00:00:00 2001 From: Pranith Kumar Date: Mon, 26 Jan 2015 12:58:43 -0800 Subject: printk: add dummy routine for when CONFIG_PRINTK=n There are missing dummy routines for log_buf_addr_get() and log_buf_len_get() for when CONFIG_PRINTK is not set causing build failures. This patch adds these dummy routines at the appropriate location.
