Subject: [PATCH 04/13] target/mips: Remove access_type argument from get_physical_address()
Date: Thu, 28 Jan 2021 15:41:16 +0100 [thread overview]
Message-ID: <20210128144125.3696119-5-f4bug@amsat.org> (raw)
In-Reply-To: <20210128144125.3696119-1-f4bug@amsat.org>
get_physical_address() doesn't use the 'access_type' argument,
remove it to simplify.
