This series does some minimal cleanups.
	-Conversion of pr_*() to dev_*()
	-Convert kzalloc to devm_kzalloc.

No functional changes.

v1 -> v2 Address review comments.
v2 -> v3 Remove a stale commit comment.

George Cherian (3):
  driver net: cpsw: Convert pr_*() to dev_*() calls
  net: davinci_mdio: Convert pr_err() to dev_err() call
  drivers: net: davinci_cpdma: Convert kzalloc() to devm_kzalloc().
