3.16.50-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.
