Subject: [PATCH 10/15] net: wireless: ath: simplify return flow for carl9170_regwrite_result()

This patch is to the carl9170/phy.c file that fixes warning reported by
coccicheck :

 WARNING: end returns can be simplified

I have removed unneccessary variable declaration and simply return flow
for carl9170_regwrite_result()
