Fix a possible copy-paste error in arm_smccc_smc's first argument (a0) for OPTEE_SMC_DISABLE_SHM_CACHE case.
This error causes Linux > v5.14-rc5 (b5c10dd04b7418793517e3286cde5c04759a86de optee: Clear stale cache entries during initialization) to stuck repeatedly issuing OPTEE_SMC_DISABLE_SHM_CACHE call and waiting for the result to be OPTEE_SMC_RETURN_ENOTAVAIL which will never happen.

I added Fixes: and Backport: tags to the commit
Per SUPPORT.MD, OP-TEE is still a technical preview. So I would argue that we should not do any backport because the feature itself is not officially considered supported.
That said, what's missing to make the feature officially supported?
Cheers,
