ACPI / LPSS: drop clkdev_name member from lpss_device_desc (b0d00f8b) · Commits · 戴 / test

It was used to provide the correct con_id for the dma driver, but it's not needed. Even if the driver requests a clock with the con_id, it still gets the correct clock. The device name is enough to match a single clock. Signed-off-by:
