Subject: [PATCH v2 03/13] drivers/acpi: convert seqno seqnum_ops
Date: Fri, 13 Nov 2020 10:46:05 -0700 [thread overview]
Message-ID: <b0bed077dd48518f10195844b5bb0ac4374df868.1605287778.git.skhan@linuxfoundation.org> (raw)
In-Reply-To: <cover.1605287778.git.skhan@linuxfoundation.org>
Sequence Number api provides interfaces for unsigned atomic up counters
leveraging atomic_t and atomic64_t ops underneath.
Convert seqno atomic counter to use seqnum_ops.
