[PATCH v4 0/4] Add support for rotation from north to the hid-sensor-magn-3d driver

[Reyad Attiyat <reyad.attiyat@gmail.com>]

This version of patches tries to make smaller changes to the magn-3d driver. It
scans for usages present in the magn_3d_addresses array. It then allocates
memory for the IIO channel structs and value arrays that are used in the IIO subsystem.
It sets-up each IIO channel struct by copying the values from the static array of
IIO configurations. There is also an array used to store each channel IIO value
pointer for each HID usage attribute.
