The function drbg_generate_long slices the request into 2**16 byte
or smaller chunks. However, the loop, however invokes the random number
generation function with zero bytes when the request size is a multiple
of 2**16 bytes. The fix prevents zero bytes requests.

The kgdb breakpoint hooks (kgdb_brk_fn and kgdb_compiled_brk_fn) should only be
entered when a kgdb break instruction is executed from the kernel. Otherwise,
if kgdb is enabled, a userspace program can cause the kernel to drop into the
debugger by executing either KGDB_BREAKINST or KGDB_COMPILED_BR
Check for cases when the caller requests 0 bytes instead of running off
and dereferencing potentially invalid iovecs.

As per Ian, at this point in time it is not worth implementing an async
command interface for diagnostic interrupts for this board. As this is
the case, this patch removes the code which supports such interrupts as it
is now unused.
This includes removing apci1564_do_read(), which was the insn_re
This board provides VCC/CC diagnostic information, and it also supports
diagnostic interrupts. However, as per Ian, these interrupts aren't very
useful and it is enough to simply provide an interface for accessing the
diagnostic status on-demand. This patch adds a 2-channel digital input
subdevic
This patchset creates a simple subdevice to allow for reading of the
board's diagnostic status, and then removes any code which is related to
diagnostic interrupts, as the driver will not support these at this time.

INT3438 is the ADSP device on Wildcat Point platform
with 2 DW DMA engines built In. The DMA engines are
used for DSP FW loading and audio data transferring.
These DMA engine probing need the clock, without it,
probing may failed and can't go forward.
Add lpss device "INT3438" for Wildcat Point PC
