Subject: [PATCH 4.2 026/120] iio:accel:mma8452: fix _get_hp_filter_index

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hartmut Knaack <knaack.h@....de>

commit 001fceb9c64a39aebb85d31134182d39c1628a21 upstream.

To iterate through the available frequencies of mma8452_hp_filter_cutoff[],
the array size of a row of that table needs to be provided to
_get_int_plus_micros_index().

Fixes: 	1e79841a00e46 ("iio: mma8452: Add highpass filter configuration.")
