Subject: [can-next-rfc 9/9] can: peak_pci: Add name and FW version of the card in kernel buffer
Date: Wed, 16 Jun 2021 12:28:11 +0200 [thread overview]
Message-ID: <20210616102811.2449426-10-mkl@pengutronix.de> (raw)
In-Reply-To: <20210616102811.2449426-1-mkl@pengutronix.de>
From: Stephane Grosjean <s.grosjean@peak-system.com>
This patch adds name and (possibly) firmware version information to
the kernel about the detected PEAK-System CAN - PCI/PCIe interface
card.
