Dmitry Torokhov 867e8820e0 Input: mma8450 - switch to using polled mode of input devices
We have added polled mode to the normal input devices with the intent of
retiring input_polled_dev. This converts mma8450 driver to use the polling
mode of standard input devices and removes dependency on INPUT_POLLDEV.

Dmitry Torokhov 5037a17966 Input: mma8450 - convert to using managed resources
This simplifies error handling and device removal code. Also let's
get rid of setting driver's owner since i2c core does it for us.

Stefan Sauer 71daf89476 Input: mma8450 - add parent device
Add the parent device so that udev can show the full hierarchy. This avoids
the device showing up under /devices/virtual/input instead of the i2c bus
it is actually attached to.

Add missing i2c_set_clientdata() in mma8450_probe(), otherwise
calling i2c_get_clientdata() in mma8450_remove() returns NULL.

Sebastien Royen 257a1ec603 Input: mma8450 - fix signed 12bits to 32bits conversion
Event value is wrong. Should be in range -2048 to 2047, but is in
range 0 to 4095.  Use s8 to int conversion and remove 0xfff mask.
