Subject: [PATCH AUTOSEL 6.6 02/20] usb: storage: sddr55: fix sloppy typing in sddr55_{read|write}_data()
Date: Wed, 3 Apr 2024 13:17:43 -0400 [thread overview]
Message-ID: <20240403171815.342668-2-sashal@kernel.org> (raw)
In-Reply-To: <20240403171815.342668-1-sashal@kernel.org>
From: Karina Yankevich <k.yankevich@omp.ru>
[ Upstream commit d6429a3555fb29f380c5841a12f5ac3f7444af03 ]
In sddr55_{read|write}_data(), the address variables are needlessly typed
as *unsigned long* -- which is 32-bit type on the 32-bit arches and 64-bit
type on the 64-bit arches; those variables' value should fit into just 3
command bytes and consists of 10-bit block # (or at least the max block #
seems to be 1023) and 4-/5-bit page # within a block, so 32-bit *unsigned*
*int* type should be more than enough...
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
