[PATCH v3 0/3] IIO: Add support for rotation from north usage attributes

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

These patches add support for rotation from north HID usage attributes to
the magnetometer 3d driver.

Changes from v2:
	Use devm_kcalloc for all dynamic allocations
	Cleanup formatting of if statements
	Scan for the usage attributes present then dynamically allocate iio channel and value arrays
	Use proper return errors (-EINVAL) and (-ENOMEM)
