[PATCH] iio: accel: bma180: Convert enum->pointer for data in the match table

[Biju Das]

Convert enum->pointer for data in the match table, so that
device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c
bus type match support added to it.

Replace enum->struct *bma180_part_info for data in the match table and
simplify bma180_probe().
