Subject: tee: optee: fix uuid comparisons on service discovery
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=eda976d36a37d459da5908fb922173a4bafe8666;p=u-boot.git

tee: optee: fix uuid comparisons on service discovery

When comparing UUIDs for discovered services we only compare up to the
ptr size instead of the entire UUID

Fixes: 94ccfb78a4d61 ("drivers: tee: optee: discover OP-TEE services")
