Subject: [PATCH 4.14 v2 ] platform/x86: Corrects warning: missing braces around initializer

From: John Donnelly <john.p.donnelly@...cle.com>

The assignment statement of a local variable "struct tp_nvram_state s[2] = {0};
is not valid for all versions of compilers.

Fixes: 515ded02bc4b ("platform/x86: thinkpad_acpi: initialize tp_nvram_state variable")
