ath6kl: fix return value in ath6kl_wmi_set_pvb_cmd
When building with W=1, we got one warning as belows: drivers/net/wireless/ath/ath6kl/wmi.c:3509:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] At the end of ath6kl_wmi_set_pvb_cmd, it is returned by 0 regardless of return value of ath6kl_wmi_cmd_send. This patch fixes return value from 0 to ret that has result of ath6kl_wmi_cmd_send execution. Signed-off-by: Chaehyun Lim <chaehyun.lim@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
