Suggest improvement to ar5416_ani.c on adaptive noise immunity

[Winston h01i]

I was reading the source code in the ar5416_ani.c file and I would
like to suggest an improvement.

http://svnweb.freebsd.org/base/projects/bmake/sys/dev/ath/ath_hal/ar5416/ar5416_ani.c?view=markup


Code:
---------
966    params = aniState->params;
967    if (aniState->listenTime > 5*params->period) {
968            /*
969            * Check to see if need to lower immunity if
970            * 5 aniPeriods have passed
971            */
972            updateMIBStats(ah, aniState);
973            if (aniState->ofdmPhyErrCount <= aniState->listenTime *
974                params->ofdmTrigLow/1000 &&
975                aniState->cckPhyErrCount <= aniState->listenTime *
976                params->cckTrigLow/1000)
977                    ar5416AniLowerImmunity(ah);
978            HALDEBUG(ah, HAL_DEBUG_ANI, "%s: lower immunity\n",
979                __func__);
980            ar5416AniRestart(ah, aniState);
981    } else if (aniState->listenTime > params->period) {
---------
I think lines 977 to 979 should be grouped together by curly braces.

The reason is that currently line 978 is outside of the "if" block
starting in line 973.
