In some configurations the inlining in gcc is suboptimal, causing
a false-positive warning:
drivers/net/wireless/ath/ath10k/mac.c: In function 'ath10k_mac_init_rd':
drivers/net/wireless/ath/ath10k/mac.c:8374:39: error: 'rd' may be used uninitialized in this function [-Werror=maybe-uninitialized]
ar->ath_common.regulatory.current_rd = rd;
If we initialize the output of ath10k_mac_get_wrdd_regulatory()
before returning, this problem goes away.
