[PATCH] udmabuf: fix odd_ptr_err.cocci warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: kbuild test robot <fengguang.wu@xxxxxxxxx>

drivers/dma-buf/udmabuf.c:167:6-12: inconsistent IS_ERR and PTR_ERR on line 168.

 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 to
 IS_ERR that is wrong.

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

Fixes: cc2d0e91bc15 ("udmabuf: driver update")
