Subject: [PATCH net-next] pps: bump PPS device count
Date: Fri, 15 May 2026 13:50:28 +0000 [thread overview]
Message-ID: <20260515135028.2021318-1-vadim.fedorenko@linux.dev> (raw)
Modern systems may have more than 16 PPS sources and current hard-coded
limit breaks registration of some devices. Let's bump the limit to 256
in hope it will be enough in foreseen future.
