Subject: [PATCH 02/11] firmware: qemu_fw_cfg: drop duplicate definitions
Date: Thu, 13 Mar 2025 11:17:19 +0100 [thread overview]
Message-ID: <20250313101728.3546902-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20250313101728.3546902-1-a.fatoum@pengutronix.de>
These same defines are already in <uapi/linux/qemu_fw_cfg.h>, so let's
not duplicate them in the driver.
