From bf9ca69fc8d19d4034391d3df4c35dccdef9d28c Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 30 Jul 2008 12:29:21 -0700 Subject: [PATCH] dev_printk(): constify the `dev' argument Add const markings to dev_name and dev_driver_string to make it clear that dev_printk doesn't modify dev. This is a prerequisite to adding more const markings to other functions make it clearer, which functions can modify dev and which can't.
