[PATCH 3.2 123/147] platform/x86: samsung-laptop: Initialize loca variable

[Ben Hutchings]

3.2.95-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

commit 0d2c95354a3b63256e92d9fb865c08902d2c9b0b upstream.

The variable is used uninitialized which might come into unexpected
behaviour on some Samsung laptops.

Initialize it to 0xffff which seems a proper value for non-supported
feature.
