Subject: [PATCH 1/2] staging: vme_user: Replace printk() with pr_*(),dev_*()

vme.c uses printk() to log messages. To improve and standardize message
formatting, use logging mechanisms pr_err()/pr_warn() and
dev_err()/dev_warn() instead. Retain the printk log levels of the
messages during replacement.
