Subject: commands/efi/tpm: Use grub_strcpy() instead of grub_memcpy()
X-Git-Tag: grub-2.12-rc1~306
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ef8679b645a63eb9eb191bb9539d7d25a9d6ff3b;p=thirdparty%2Fgrub.git

commands/efi/tpm: Use grub_strcpy() instead of grub_memcpy()

The event description is a string, so using grub_strcpy() is cleaner than
using grub_memcpy().
