Subject[PATCH] iio: accel: mma8452: Constify static struct attribute_group
Date
The only usage of mma8452_event_attribute_group is to assign its address
to the event_attrs field in the iio_info struct, which is a const
pointer. Make it const to allow the compiler to put it in read-only
memory. This was the only non-const static struct in drivers/iio.
