Zero-length arrays as fake flexible arrays are deprecated and we are moving towards adopting C99 flexible-array members instead. Address the following warning found with GCC-13 and -fstrict-flex-array=3 enabled: drivers/net/wireless/rndis_wlan.c:2902:23: warning: array subscript 0 is outside array bounds of ‘struct ndis_80211_auth_request[0]’ [-Warray-bounds=] This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].
