From: Kalle Valo <quic_kvalo@xxxxxxxxxxx> I updated to sparse v0.6.4 and it warns: drivers/net/wireless/ath/ath10k/wmi.c: note: in included file (through drivers/net/wireless/ath/ath10k/core.h): drivers/net/wireless/ath/ath10k/wmi.h:3481:34: warning: array of flexible structures Fix it by changing the type to u8 array, in struct wmi_phyerr_hdr_arg it's stored as a void pointer anyway. Compile tested only.
