Subject: [PATCH v2 1/2] printk: Add dummy routine for when CONFIG_PRINTK=n
Date: Wed, 21 Jan 2015 21:26:08 -0500	[thread overview]
Message-ID: <1421893570-6920-1-git-send-email-bobby.prani@gmail.com> (raw)

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.
