From 44c5027bb5c8bbdc2aea2141dc32fe72c3f3988a Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Tue, 27 Apr 2021 18:59:13 -0500 Subject: scsi: 3w-9xxx: Use flexible array members to avoid struct padding In preparation for removing the "#pragma pack(1)" from the driver, fix all instances where a trailing array member could be replaced by a flexible array member. Since a flexible array member has zero size, it introduces no padding, whether or not the struct is packed.
