Subject: iio: accel: bma400: Fix memory leak in bma400_get_steps_reg()
From: Dong Chenchen <dongchenchen2@xxxxxxxxxx>
commit 20690cd50e68c0313472c7539460168b8ea6444d upstream.
When regmap_bulk_read() fails, it does not free steps_raw,
which will cause a memory leak issue, this patch fixes it.
Fixes: d221de60eee3 ("iio: accel: bma400: Add separate channel for step counter")
