Subject: [PATCH 1/3] scsi: qla2xxx: Replace vmalloc + memset with vzalloc
Date: Thu, 18 Jul 2019 15:45:18 +0800 [thread overview]
Message-ID: <20190718074518.16273-1-hslester96@gmail.com> (raw)
Use vzalloc instead of using vmalloc to allocate memory
and then zeroing it with memset.
This simplifies the code.
