Tom Lendacky afb31cd2d1 crypto: ccp - Check for NULL PSP pointer at module unload ... Should the PSP initialization fail, the PSP data structure will be freed and the value contained in the sp_device struct set to NULL. At module unload, psp_dev_destroy() does not check if the pointer value is NULL and will end up dereferencing a NULL pointer. Add a pointer check of the psp_data field in the sp_device struct in psp_dev_destroy() and return immediately if it is NULL.
