9e40ff1f78 atomisp: kill another define
We don't need an ifdef for the sake of 8-12 bytes. Avoid the ifdef added by
fde469701c7efabebf885e785edf367bfb1a8f3f. Instead turn it into a single const
string array at a fixed location thereby saving even more memory.

447a7f934e staging: media: atomisp: fix build errors when PM is disabled
The function atomisp_restore_iumit_reg is unused when PM is disabled.
Adding __maybe_unused to the function definition avoids a warning.

The function atomisp_mrfld_power_down is defined only when PM is
enabled. So in atomisp_pci_probe, it should be called only when PM is
enabled.

9b7edbb60b staging/atomisp: add ACPI dependency
Without ACPI, some of the code fails to build:

media/atomisp/platform/intel-mid/atomisp_gmin_platform.c: In function 'atomisp_register_i2c_module':
media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:174:7: error: dereferencing pointer to incomplete type 'struct acpi_device'

We could work around that in the code, but since we already have a hard
dependency on x86, adding the ACPI dependency seems to be the easiest
solution.

19740d6840 staging/atomisp: add PCI dependency
Without CONFIG_PCI, config space reads never return any data,
leading to undefined behavior that gcc warns about:

platform/intel-mid/intel_mid_pcihelpers.c:137:9: error: 'data' is used uninitialized in this function [-Werror=uninitialized]

With a dependency on CONFIG_PCI, we don't get this warning. This seems
safe as PCI config space accessors should always return something
when PCI is enabled.

72d2b01e84 staging/atomisp: fix empty-body warning
Defining a debug function to nothing causes a warning with an empty block
after if()/else():

drivers/staging/media/atomisp/i2c/ov2680.c: In function 'ov2680_s_stream':
drivers/staging/media/atomisp/i2c/ov2680.c:1208:55: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]

This changes the empty debug statement to dev_dbg(), which by default also
does nothing, but avoids this warning and also checks the format string.
As a side-effect, we can now use dynamic debugging to turn on the
output at runtime.

Our driver only ever uses one set of routines for the allocators used by the CSS layer to
manage memory and the memory management on the ISP. We can thus remove the function vectors
and simply call the intended routines directly.

These routines in turn are simply wrappers around another layer of code so remove this
second layer of wrappers and call the hrt methods directly. In time we can remove this layer
of indirection as well.

dd1c0f278b staging: media: atomisp: fix build error in ov5693 driver
The ov5693 driver unconditionally uses the entity member of struct v4l2_subdev.
However this member is conditionally compiled in if CONFIG_MEDIA_CONTROLLER is
set. This results in the following build error if CONFIG_MEDIA_CONTROLLER is
not set:

drivers/staging/media/atomisp/i2c/ov5693/ov5693.c: In function 'ov5693_remove':
drivers/staging/media/atomisp/i2c/ov5693/ov5693.c:1961:31: error: 'struct v4l2_subdev' has no member named 'entity'
  media_entity_cleanup(&dev->sd.entity);

drivers/staging/media/atomisp/i2c/ov5693/ov5693.c:2023:9: error: 'struct v4l2_subdev' has no member named 'entity'
  dev->sd.entity.function = MEDIA_ENT_F_CAM_SENSOR;
         ^
drivers/staging/media/atomisp/i2c/ov5693/ov5693.c:2045:39: error: 'struct v4l2_subdev' has no member named 'entity'
  ret = media_entity_pads_init(&dev->sd.entity, 1, &dev->pad);

Add the corresponding Kconfig dependency to solve this error.

bc44a73e17 Staging: atomisp: kfreeing a devm allocated pointer
We shouldn't pass devm allocated pointers to kfree() or it leads to a
double free.
