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