platform/x86: thinkpad_acpi: initialize tp_nvram_state variable commit 5f38b06db8af3ed6c2fc1b427504ca56fae2eacc upstream. clang static analysis flags this represenative problem thinkpad_acpi.c:2523:7: warning: Branch condition evaluates to a garbage value if (!oldn->mute || ^~~~~~~~~~~ In hotkey_kthread() mute is conditionally set by hotkey_read_nvram() but unconditionally checked by hotkey_compare_and_issue_event(). So the tp_nvram_state variable s[2] needs to be initialized.
