Subject: [PATCH v2 1/2] x86/sgx: Add the missing ifdef for sgx_set_attribute()
Date: Thu, 19 Aug 2021 15:48:23 +0300 [thread overview]
Message-ID: <20210819124824.52169-1-jarkko@kernel.org> (raw)
Similarly as sgx_virt_*, decorate sgx_set_attribute() with ifdef, so that
calling it without appropraite config flags, will cause a compilation
error, and not a linking error.
Fixes: b3754e5d3da3 ("x86/sgx: Move provisioning device creation out of SGX driver")
