Subject: iio: accel: bma180: Convert enum->pointer for data in the match table
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fe11e389117a6d98a8a5c894f69975877c612d67;p=linux.git

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

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().
