e2527ec369 drivers/misc: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

d396034aa8 drivers: misc: bmp085: remove '__init' from mp085_get_of_properties()
bmp085_get_of_properties() is called by bmp085_init_client() which is
called by bmp085_probe() which is an EXPORT_SYMBOL_GPL function.

bmp085_probe() is really used as a probe function by another modules
(e.g. bmp085-i2c.c, bmp085-spi.c).

Except bmp085_get_of_properties(), all functions have no '__init', so
need remove '__init' from bmp085_get_of_properties() too, or at least,
it will report related warning:

  WARNING: vmlinux.o(.text+0x4c8a07): Section mismatch in reference from the variable .LM171 to the variable .init.text:_bmp085_get_of_properties
  The function .LM171() references
  the variable __init _bmp085_get_of_properties.
  This is often because .LM171 lacks a __init
  annotation or the annotation of _bmp085_get_of_properties is wrong.

985087dbcb misc: add support for bmp18x chips to the bmp085 driver
The bmp18x chip family comes in an I2C respectively SPI variant.
Hence, the bmp085 driver was split to support both buses.

This patch converts the drivers in drivers/misc/* to use the
module_i2c_driver() macro which makes the code smaller and a bit

5bf1d290b5 drivers/misc: support for the pressure sensor BMP085 from Bosch Sensortec
This driver adds support for the BMP085 digital pressure sensor from Bosch
Sensortec.  It exposes a sysfs api to userspace where pressure and
temperature measurement results can be read from the pressure0_input and
temp0_input file.  The chip is able to calculate the average of up to
eight samples to increase the accuracy.  This feature can be controlled by
writing to the oversampling file.

The BMP085 digital pressure sensor can measure ambient air pressure and
temperature.  Both values can be obtained from sysfs files.  The pressure
is measured by reading from pressure0_input.  Valid values range from
30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar).

temp0_input holds the current temperature in degree celsius, multiplied by
10.  This results in a resolution of a tenth degree celsius.  Values range
from -400 to 850.

To increase the accuracy, this chip can calculate the average of 1, 2, 4
or 8 samples.  This behavior is controlled through the oversampling sysfs
file.  Two to the power of the value written to that file specifies how
many samples will be used.  Valid values: 0..3.
