Subject: tee: optee: don't fail probe because of optee-rng
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=476a3d58dfeb6230f44b629e5791d70f0e55d78f;p=u-boot.git

tee: optee: don't fail probe because of optee-rng

Fixes optee-rng driver bind sequence in optee driver to print a warning
message but not report an error status when a optee-rng service driver
fails to be bound as the optee driver itself is still fully functional.
