If anyone has any objections, please let me know. ------------------ From: Nicolas Iooss commit a3fa71c40f1853d0c27e8f5bc01a722a705d9682 upstream. In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an array, not a number. This means WL18XX_DEBUGFS_FWSTATS_FILE can't be used to display this field in debugfs (it would display a pointer, not the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead. This bug has been found by adding a __printf attribute to wl1271_format_buffer. gcc complained about "format '%u' expects argument of type 'unsigned int', but argument 5 has type 'u32 *'".
