The 'buf' variable is only used in the USB (if-path) and not in the Bluetooth
else-path. Since it is not set to NULL. this results in freeing an uninitialized
pointer. Since the else code-path doesn't need buf, just return 0.

Add support for 3x 10-bit ADC and 1x DAC channels registered via the iio
subsystem.
To prevent breakage and unexpected dependencies this support only is
only built if CONFIG_IIO is enabled, and is only weakly referenced by
'imply IIO' within the respective Kconfig.
Additionally the iio device only gets registered if at least one channel
is enabled in the power-on configuration read from SRAM.

To avoid recursive dependencies on GPIOLIB when 'imply IIO' is requested
with other drivers we should switch GPIOLIB to an imply.
This isn't the most ideal solution but avoids modifiying the Kconfig for

The Topre REALFORCE R2 firmware incorrectly reports that interface
descriptor number 1, input report descriptor 2's events are array events
rather than variable events. That particular report descriptor is used
to report keypresses when there are more than 6 keys held at a time.
This bug prevents events from this interface from being registered
properly, so only 6 keypresses (from a different interface) can be
registered at once, rather than full n-key rollover.
This commit fixes the bug by setting the correct value in a report_fixup
function.

This patch adds support for controller rumble.
The ff_effect weak magnitude is associated with the pro controller's
right motor (or with a right joy-con). The strong magnitude is
associated with the pro's left motor (or a left joy-con).
The rumble data is sent periodically (currently configured for every 50
milliseconds). If the controller receives no rumble data for too long a
time period, it will stop vibrating. The data is also sent every time
joycon_set_rumble is called to avoid latency of up to 50ms.
Because the rumble subcommands are sent in a deferred workqueue (they
can't be sent in the play_effect function due to the hid send sleeping),
the effects are queued. This ensures that no rumble effect is missed due
to them arriving in too quick of succession.

A number of USB keyboards, using the Semitek firmware, are capable of
handling arbitrary N-key rollover, but due to a buggy report
descriptor, keys beyond the sixth cannot be detected by the generic
HID driver.
There are numerous hardware variants sold by several vendors, mostly
using generic names like "GK61" for the 61-key version. These
keyboards are sometimes known collectively as the "GK6X" series.
The keyboard has three USB interfaces. Interface 0 uses the standard
HID boot protocol, limited to eight modifier keys and six normal keys;
interface 2 uses a custom report format that permits any number of
keys. If more than six keys are pressed simultaneously, the first six
are reported via interface 0 while subsequent keys are reported via
interface 2.
(Interface 1 uses a custom protocol for reprogramming the keyboard;
this can be controlled through userspace tools and is not of concern
for the present driver.)
The report descriptor for interface 2, however, is incorrect (for
report ID 0x04, the input field is marked as "array" rather than
"variable".) The descriptor appears to be correct in other respects,
so we simply replace the incorrect byte before parsing the descriptor.
