Subject: [PATCH 3.14 27/35] Input: tegra-kbc - fix inverted reset logic

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

commit fae16989be77b09bab86c79233e4b511ea769cea upstream.

Commit fe6b0dfaba68 ("Input: tegra-kbc - use reset framework")
accidentally converted _deassert to _assert, so there is no code
to wake up this hardware.

Fixes: fe6b0dfaba68 ("Input: tegra-kbc - use reset framework")
