Hello there,
[linux-4.0-rc1/drivers/net/wireless/ath/wil6210/debugfs.c:634]: (error) Width 8 given in format string (no. 1) is larger than destination buffer 'cmd[8]', use %7s to prevent overflowing it.
This looks like an off-by-one error to me.
Suggest either make the buffer bigger, to contain all 8 characters,
or change the width to suit.
Regards
David Binderman
