Tom Lendacky f831d2882c crypto: ccp - During shutdown, check SEV data pointer before using ... [ Upstream commit 1b05ece0c9 ] On shutdown, each CCP device instance performs shutdown processing. However, __sev_platform_shutdown_locked() uses the controlling psp structure to obtain the pointer to the sev_device structure. However, during driver initialization, it is possible that an error can be received from the firmware that results in the sev_data pointer being cleared from the controlling psp structure. The __sev_platform_shutdown_locked() function does not check for this situation and will segfault. While not common, this scenario should be accounted for. Add a check for a NULL sev_device structure before attempting to use it.
