ASoC: Fixes for v4.3 

A disappointingly large set of fixes, though none of them very big and
 very widely spread over many different drivers.  Nothing especially
 stands out, it's mostly all device specific and relatively minor.

power = gpiod_get(dev, "power", GPIOD_OUT_HIGH);
The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
gpiod_is_active_low(power) will be true).
The second parameter of the gpiod_get() functions, the con_id string, has to be
the <function>-prefix of the GPIO suffixes ("gpios" or "gpio", automatically
looked up by the gpiod functions internally) used in the device tree. With above
"led-gpios" example, use the prefix without the "-" as con_id parameter: "led".
Internally, the GPIO subsystem prefixes the GPIO suffix ("gpios" or "gpio")
with the string passed in con_id to get the resulting string
(snprintf(... "%s-%s", con_id, gpio_suffixes[]).
ACPI

ACPI also supports function names for GPIOs in a similar fashion to DT.

struct gpio_desc *red, *green, *blue, *power;
red = gpiod_get_index(dev, "led", 0);

blue = gpiod_get_index(dev, "led", 2);
red = gpiod_get_index(dev, "led", 0, GPIOD_OUT_HIGH);
green = gpiod_get_index(dev, "led", 1, GPIOD_OUT_HIGH);

power = gpiod_get(dev, "power");
gpiod_direction_output(power, 1);
power = gpiod_get(dev, "power", GPIOD_OUT_HIGH);
Since the "power" GPIO is mapped as active-low, its actual signal will be 0
after this code. Contrary to the legacy integer GPIO interface, the active-low
property is handled during mapping and is thus transparent to GPIO consumers.
Since the "led" GPIOs are mapped as active-high, this example will switch their
signals to 1, i.e. enabling the LEDs. And for the "power" GPIO, which is mapped
as active-low, its actual signal will be 0 after this code. Contrary to the legacy
integer GPIO interface, the active-low property is handled during mapping and is
thus transparent to GPIO consumers.

help
This option builds kernel modules using the large memory model in
order to avoid the use of the ADRP instruction, which can cause
a subsequent memory access to use an incorrect address on Cortex-A53
parts up to r0p4.
Note that the kernel itself must be linked with a version of ld
which fixes potentially affected ADRP instructions through the
use of veneers.
If unsure, say Y.
