Subject: [PATCH] ASoC: atmel-classd: fix odd_ptr_err.cocci warnings

sound/soc/atmel/atmel-classd.c:578:5-11: inconsistent IS_ERR and PTR_ERR, PTR_ERR on line 579

 PTR_ERR should access the value just tested by IS_ERR

Semantic patch information:
 There can be false positives in the patch case, where it is the call
 IS_ERR that is wrong.

Generated by: scripts/coccinelle/tests/odd_ptr_err.cocci
