Subject: [PATCH 0/2][next] wifi: brcmfmac: common: Replace one-element array
 with flexible-array member

Hi!

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].
