From: Xiaoke Wang <xkernel.wang@xxxxxxxxxxx>
devm_kstrdup() returns pointer to allocated string on success,
NULL on failure. So it is better to check the return value of it.

Changelogs:
1. Use my official name.
2. Synchronize with the latest source code(kstrdup -> devm_kstrdup).
3. Clear up useless code(devm_kfree).
