Subject: stm32mp1: zeromem device_info struct
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=42beea8d70804e9b9f7f87e7c7ef0b95d824ce09;p=project%2Fbcm63xx%2Fatf.git

stm32mp1: zeromem device_info struct

The change of the structure highlighted the fact that all fields are not
correctly initialized with zeroes.

Replace the other memset in the function with zeromem, as it is faster.
