Hi Tom,
this looks good. But this patch applied, and with clang 11.0.2,
make CC=clang W=1 tells me:
drivers/net/wireless/ath/ath10k/ce.c:80:19: error: unused function 'shadow_dst_wr_ind_addr' [-Werror,-Wunused-function]
static inline u32 shadow_dst_wr_ind_addr(struct ath10k *ar,
^
drivers/net/wireless/ath/ath10k/ce.c:434:20: error: unused function 'ath10k_ce_error_intr_enable' [-Werror,-Wunused-function]
static inline void ath10k_ce_error_intr_enable(struct ath10k *ar,
^
Perhaps those functions should be removed too?

Sorry, my bad. You are correct.
Patch looks good to me (now).
