[PATCH] [v2] Input: stmpe-ts - mark OF related data as maybe unused

[Arnd Bergmann]

From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

When compile tested with W=1 on x86_64 with driver as built-in:

  stmpe-ts.c:371:34: error: unused variable 'stmpe_ts_ids' [-Werror,-Wunused-const-variable]

Ideally this would be referenced from the platform_driver, but since
the compatible string is already matched by the mfd driver for its
parent device, that would break probing.

In this case, the of_device_id table just serves as a module alias
for loading the driver, while the device itself is probed using
the platform device name.
