From: Mauro Carvalho Chehab Date: Thu, 13 Oct 2016 09:47:54 +0000 (-0300) Subject: [media] dvb-core: use pr_foo() instead of printk() X-Git-Tag: v4.10-rc1~71^2^2~486 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3ad24d2e0b039834db28d06727dc9a675aa0396;p=karo-tx-linux.git [media] dvb-core: use pr_foo() instead of printk() The dvb-core directly calls printk() without using the modern printk macros, or using the proper printk levels. Change it to use pr_foo().
