#1422692 — [PATCH 3.12 39/56] rtlwifi: Fix logic error in enter/exit power-save mode

From: wang yanqing <udknight@gmail.com>

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

===============

commit 873ffe154ae074c46ed2d72dbd9a2a99f06f55b4 upstream.

In commit a269913c52ad ("rtlwifi: Rework rtl_lps_leave() and
rtl_lps_enter() to use work queue"), the tests for enter/exit
power-save mode were inverted. With this change applied, the
wifi connection becomes much more stable.
