Subject: tee: optee: don't fail on services enumeration failure
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=ab9500e9c3fa1a4512eeebcc616f7ba73cf938ef;p=u-boot.git

tee: optee: don't fail on services enumeration failure

Change optee probe function to only warn when service enumeration
sequence fails instead of reporting an optee driver probe failure.
Indeed U-Boot can still use OP-TEE even if some OP-TEE services are
not discovered.

Fixes: 94ccfb78a4d6 ("drivers: tee: optee: discover OP-TEE services")
