Subject: [PATCH tip/core/rcu 1/5] module: Fix pr_fmt() bug for header use of printk
Date: Mon, 24 Jul 2017 14:58:13 -0700 [thread overview]
Message-ID: <1500933497-12612-1-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170724215758.GA12075@linux.vnet.ibm.com>
From: Joe Perches <joe@perches.com>
This commit removes the pr_fmt() macro, replacing it with mod_err() and
mod_debug() macros to avoid errors when using printk() from header files.
