platform/x86/intel/vsec: Use mutex for ida_alloc() and ida_free()
mainline inclusion from mainline-v6.3-rc1 commit 9a90ea7d category: feature bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I8WOEC Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9a90ea7d378486aa358330dafc7e8c3b27de4d84 ------------------------------------- ID alloc and free functions don't have in built protection for parallel invocation of ida_alloc() and ida_free(). With the current flow in the vsec driver, there is no such scenario. But add mutex protection for potential future changes. Intel-SIG: commit 9a90ea7d platform/x86/intel/vsec: Use mutex for ida_alloc() and ida_free(). Backport Intel_vsec bus update as TPMI driver dependency.
