This series aims to replace a one-element array with flexible-array member in drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h (in struct brcmf_dload_data_le) and use the struct_size() helper. 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].
