If anyone has any objections, please let me know. ------------------ From: Dan Carpenter commit b2a72ec32d0f499aaadf41264232517a12326df0 upstream. qla2x00_mem_alloc() returns 1 on success and -ENOMEM on failure. On the one hand the caller assumes non-zero is success but on the other hand the caller also assumes that it returns an error code. I've fixed it to return zero on success and a negative error code on failure. This matches the documentation as well.
