android12-trusty-5.10 needs to rebase to the latest android12-5.10 to fix this.

This branch is meant to be merged into vendor kernels that need the
trusty driver. We should not rebase it as that could create merge
conflicts. We could merge android12-5.10 but we don't have a good
reason to do so at this time as downstream branches already merge
android12-5.10 directly. The android12-trusty-5.10 branch itself is
only used to build the linux kernel for our emulator tests.

This branch is meant to be merged into vendor kernels that need the
trusty driver. We should not rebase it as that could create merge
conflicts. We could merge android12-5.10 but we don't have a good
reason to do so at this time as downstream branches already merge
android12-5.10 directly. The android12-trusty-5.10 branch itself is
only used to build the linux kernel for our emulator tests.
