From: Dan Carpenter Date: Tue, 21 Jan 2014 07:00:10 +0000 (+0300) Subject: [SCSI] qla2xxx: fix error handling of qla2x00_mem_alloc() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b2a72ec32d0f499aaadf41264232517a12326df0;p=linux-beck.git [SCSI] qla2xxx: fix error handling of qla2x00_mem_alloc() 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.
