This affects the output of the sunxi MMC controller driver, which now produces the rather uninformative line: [ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8 Since the virtual base address is not really interesting in the first place, let's just drop this value. The same applies to Linux' notion of the interrupt number, which is independent from the GIC SPI number. We have the physical address as part of the DT node name, which is way more useful for debugging purposes. To keep a success message in the driver, we make this purpose explicit with the word "initialized", plus print some information that is not too obvious and that we learned while probing the device: the maximum request size and whether it uses the new timing mode. So the output turns into: [ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode [ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB Signed-off-by: Andre Przywara Acked-by: Maxime Ripard --- drivers/mmc/host/sunxi-mmc.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/mmc/host/sunxi-mmc.c b/drivers/mmc/host/sunxi-mmc.c index 8e7f3e35ee3d..c18cf035ac00 100644 --- a/drivers/mmc/host/sunxi-mmc.c +++ b/drivers/mmc/host/sunxi-mmc.c @@ -1407,7 +1407,10 @@ static int sunxi_mmc_probe(struct platform_device *pdev) if (ret) goto error_free_dma; - dev_info(&pdev->dev, "base:0x%p irq:%u\n", host->reg_base, host->irq); + dev_info(&pdev->dev, "initialized, max. request size: %u KB%s\n", + mmc->max_req_size >> 10, + host->use_new_timings ?
