Date: Mon, 06 Nov 2017 23:03:02 +0000 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Mike Snitzer" <snitzer@...hat.com>, "Joe Perches" <joe@...ches.com> Subject: [PATCH 3.16 153/294] dm: convert DM printk macros to pr_<level> macros 3.16.50-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Joe Perches <joe@...ches.com> commit d2c3c8dcb5987b8352e82089c79a41b6e17e28d2 upstream. Using pr_<level> is the more common logging style. Standardize style and use new macro DM_FMT. Use no_printk in DMDEBUG macros when CONFIG_DM_DEBUG is not #defined.
