Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- Gustavo has a patch to do it for all arrays in this file, and that should get merged as well, but this simpler patch is sufficient to shut up the warning. --- drivers/net/wireless/ath/wil6210/wmi.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
