If the sensor doesn't implement support for g_frame_interval,
it won't return the expected fps rate.
Instead of keeping DFS on its minimal value (which will likely
not work), set it to the max.

Instead of having a static var to detect it, let's use the

The logic which sets the hpll_freq for BYT sets hpll_freq
to 1600MHz, but ignores it, and sets it again after reading
from-device-specific EFI vars (this time, using a default
of 2000MHz).
Remove the first set, as this will be overriden anyway.
While here, do minor adjustments on comments and on a

There's a hack at the driver that selects a different table
for a BYT tablet, which sets the maximum frequency to 320 MHz,
instead of 400 MHz.
After looking at the Intel Aero Yocto's version from:
https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/
It was noticed that this depends on an Android-specific modprobe parameter,
which uses a macro (INTEL_MID_BOARD) from this file:
arch/x86/include/asm/spid.h
>From the comments there, it looks like this macro parses a
variable passed at boot time:
cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard
The devices in question are identified there as:
INTEL_BYT_TABLET_BLK_PRO = 0x0000
INTEL_BYT_TABLET_BLK_ENG = 0x8000
Well, this is something that we don't have upstream. So,
without further details about that, we can't really parse it.
If we ever end supporting those devices with the upstream driver,
this patch can be reverted and the device can be detected
via DMI (or maybe via PCI ID?).

Checking the git history, I found a commit that disabled one such case

part of the original problem and that the others do not work either,
or have never been tested.

The struct atomisp_overlay contains overlay_start_x and overlay_start_y
fields. Instead of copying the value of the overlay_start_x field between
the two structs, the value of the overlay_start_y field of the compat
struct was copied to the overlay_start_x field of the 64-bit kernel struct
in get operation and back in put. The overlay_start_x field value was not
copied from or to the user space struct.
Fix this so that the value of overlay_start_x is copied to overlay_start_x
and the value of overlay_start_y is copied to overlay_start_y.

XNR_BLENDING_SCALE_FACTOR is BIT(13), or 8192, which will easily fit

ULONG_MAX + 1, which causes it to be larger than a signed 32-bit
integer so it gets implicitly converted.
We can avoid this by using the variable isp_scale, which holds the value
of XNR_BLENDING_SCALE_FACTOR already, where the implicit conversion from
unsigned long to s32 already happened. If that were to ever overflow,
