Subject: [PATCH] crypto: qat - relocate and rename adf_sriov_prepare_restart()
Git-commit: 16c1ed95d1c4956e428c8daa2783bcc7fa7f6fb9
Patch-mainline: v6.0-rc1
References: jsc#PED-1073
The function adf_sriov_prepare_restart() is used in adf_sriov.c to stop
and shutdown a device preserving its configuration.
Since this function will be re-used by the logic that allows to
reconfigure the device through sysfs, move it to adf_init.c and rename
it as adf_dev_shutdown_cache_cfg();
