From f57e9618738da2ec562adf2dc312070b7b9a0dec Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 24 Nov 2016 09:52:34 -0200 Subject: [PATCH] [media] ivtv: use pr_foo() instead of calling printk() directly pr_foo() provides a convenient way for printk's, enforcing that they'll all prepend the error message with the driver's name. Use it inside ivtv.
