Subject: bootstd: cros: store partition type in an efi_guid_t
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c85a05a5d87ce6f077c41d7e63a4a7953ddb351c;p=u-boot.git

bootstd: cros: store partition type in an efi_guid_t

The scan_part() function uses a struct uuid to store the little-endian
partition type GUID, but this structure should be used only to contain a
big-endian UUID. Use an efi_guid_t instead.
