Subject: [PATCH 3.11 095/272] rtlwifi: rtl8188ee: Fix smatch warning in rtl8188ee/hw.c

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

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

From: Larry Finger <Larry.Finger@...inger.net>

commit dab3df5e88b979f8d09860f873ccfaa7a55758d2 upstream.

Smatch lists the following:
  CHECK   drivers/net/wireless/rtlwifi/rtl8188ee/hw.c
drivers/net/wireless/rtlwifi/rtl8188ee/hw.c:149 _rtl88ee_set_fw_clock_on() info: ignoring unreachable code.
drivers/net/wireless/rtlwifi/rtl8188ee/hw.c:149 _rtl88ee_set_fw_clock_on() info: ignoring unreachable code.

This info message is the result of a real error due to a missing break statement
in a "while (1)" loop.
