From: Giovanni Cabiddu Date: Mon, 12 Oct 2020 20:38:40 +0000 (+0100) Subject: crypto: qat - call functions in adf_sriov if available X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=185aa9c3543e5b7303e3e9c97a9b8f06fec04afe;p=linux.git crypto: qat - call functions in adf_sriov if available Call the function configure_iov_threads(), adf_enable_vf2pf_interrupts() and adf_pf2vf_notify_restarting() only if present in the struct adf_hw_device_data of the device. This is to allow for QAT drivers that do not implement those functions.
