Subject: [PATCH 5.10.y 1/2] octeontx2: Annotate mmio regions as __iomem
Date: Thu, 23 Jul 2026 07:36:34 -0400 [thread overview]
Message-ID: <20260723113635.3034593-1-sashal@kernel.org> (raw)
In-Reply-To: <2026072014-quake-amber-fee6@gregkh>
From: Subbaraya Sundeep <sbhatta@marvell.com>
[ Upstream commit d0976b43956ee8c8bd093223df9115bfcf63dfe5 ]
This patch removes unnecessary typecasts by marking the
mbox_regions array as __iomem since it is used to store
pointers to memory-mapped I/O (MMIO) regions. Also simplified
the call to readq() in PF driver by removing redundant type casts.
