Subject: igb_uio: use kernel standard log message
X-Git-Tag: spdx-start~10521
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4ca282650605f8a57d4e44fc173d828504c3937b;p=dpdk.git

igb_uio: use kernel standard log message

Use Linux kernel standard coding conventions for console messages.
Bare use of printk() is not desirable and is reported as a style
problem by checkpatch. Instead use pr_info() and dev_info()
to print out log messages where appropriate.
