Subject: [PATCH v3 2/6] scsi: megaraid_sas: Replace one-element array with flexible-array member in MR_FW_RAID_MAP_DYNAMIC
Date: Mon, 15 Aug 2022 16:42:21 -0500	[thread overview]
Message-ID: <896476f8fe43cf83b491c6c13f59c9ace780d82c.1660592640.git.gustavoars@kernel.org> (raw)
In-Reply-To: <cover.1660592640.git.gustavoars@kernel.org>

One-element arrays are deprecated, and we are replacing them with
flexible array members, instead. So, replace one-element array with
flexible-array member in struct MR_FW_RAID_MAP_DYNAMIC.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy().
