[PATCH NAND v2] mtd: nand: Replace printk() with appropriate pr_*macro()
Shreeya Patel

Mon Feb 19 05:13:45 PST 2018
The log levels embedded with the name are more concise than
printk.
Replace printks having a log level with the appropriate
pr_*macro.
Signed-off-by: Shreeya Patel <shreeya.patel23498 at gmail.com>
---
Changes in v2:
-Merge previous patches of the patchset regarding replacement
of printk with pr_*macro, into single patch.
