Subject: [PATCH] staging/vme: Use dev_ or pr_ printks in devices/vme_user.c
fixed below checkpatch warnings.
- WARNING: Prefer netdev_err(netdev, ... then dev_err(dev, ... then pr_err(... to printk(KERN_ERR ...
- WARNING: Prefer netdev_info(netdev, ... then dev_info(dev, ... then pr_info(... to printk(KERN_INFO ...
- WARNING: Prefer netdev_dbg(netdev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ...
- WARNING: Prefer netdev_warn(netdev, ... then dev_warn(dev, ... then pr_warn(... to printk(KERN_WARNING ...
and add pr_fmt.
