Subject: [PATCH v3 6/8] qla2xxx: Use scsi_get_sector() instead of scsi_get_lba()
Date: Thu, 13 May 2021 15:37:55 -0700	[thread overview]
Message-ID: <20210513223757.3938-7-bvanassche@acm.org> (raw)
In-Reply-To: <20210513223757.3938-1-bvanassche@acm.org>

Use scsi_get_sector() instead of scsi_get_lba() since the name of the
latter is confusing. Additionally, use lower_32_bits() instead of
open-coding it. This patch does not change any functionality.
