Subject: [PATCH 4/7] PCI: xilinx-nwl: Rate-limit misc interrupt messages
Date: Mon, 22 Apr 2024 15:59:01 -0400	[thread overview]
Message-ID: <20240422195904.3591683-5-sean.anderson@linux.dev> (raw)
In-Reply-To: <20240422195904.3591683-1-sean.anderson@linux.dev>

The conditions logged by the misc interrupt can occur repeatedly and
continuously. Avoid rendering the console unusable by rate-limiting
these messages.
