[PATCH 5.3 060/112] iio: accel: adxl372: Fix push to buffers lost samples

[Greg Kroah-Hartman]

From: Stefan Popa <stefan.popa@xxxxxxxxxx>

commit 62df81b74393079debf04961c48cb22268fc5fab upstream.

One in two sample sets was lost by multiplying fifo_set_size with
sizeof(u16). Also, the double number of available samples were pushed to
the iio buffers.
