Subject: [PATCH] rtlwifi: rtl8192cu: Fix duplicate if test

A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the
same condition twice. The problem was found using cppcheck-1.49, and the
proper fix was verified against the pre-mac80211 version of the code.

This patch was originally included as commit 1288aa4, but was accidentally
reverted in a later patch.

John,

Although this patch is trivial and could be included in the 3.10 stream,
I think we should not burden DaveM nor Linus with it this late in the 3.10
cycle. Please push it into the 3.11 stream.

Thanks,

Larry

You probably forgot to specify the summary line of that commit.
