Subject: [patch] [SCSI] qla4xxx: don't free NULL dma pool
Date: Wed, 30 Jan 2013 10:07:31 +0300 [thread overview]
Message-ID: <20130130070731.GC12396@elgon.mountain> (raw)
The error path calls dma_pool_free() on this path but "chap_table" is
NULL and "chap_dma" is uninitialized. It's cleaner to just return
directly.
