From 585e3227ec583217b323cec121d3fc188ca4d23e Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 14 Oct 2016 08:44:10 -0300 Subject: [PATCH] [media] dib3000mb: use pr_foo() instead of printk() The dprintk() macro relies on continuation lines. This is not a good practice and will break after commit 563873318d32 ("Merge branch 'printk-cleanups'"). So, instead of directly calling printk(), use pr_foo() macros, adding a \n leading char on each macro call. The frontend settings also rely on continuation lines. Change it to avoid the need of adding pr_cont() calls.
