    mmc: sunxi: remove output of virtual base address · 1389690b
    Andre Przywara authored
    Recent Linux versions refuse to print actual virtual kernel addresses,
    to not give a hint about the location of the kernel in a randomized virtual
    address space. 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
