Subject: iio: cros_ec: Fix the allocation size for cros_ec_command
From: Yiyuan Guo <yguoaz@xxxxxxxxx>
commit 8a4629055ef55177b5b63dab1ecce676bd8cccdd upstream.
The struct cros_ec_command contains several integer fields and a
trailing array. An allocation size neglecting the integer fields can
lead to buffer overrun.
