Subject: [PATCH v9 36/55] Input: atmel_mxt_ts - eliminate data->raw_info_block
Dynamically allocated in mxt_read_info_block() buffer buf is assigned
both to data->info and data->raw_info_block, having both data->info
and data->raw_info_block is redundant and confusing.
This patch eliminates data->raw_info_block.
