There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use flexible-array member in struct ndis_802_11_var_ie, instead of
one-element array.
Also, this helps with the ongoing efforts to enable -Warray-bounds by
fixing the following warning:
drivers/staging/rtl8188eu/core/rtw_wlan_util.c: In function ‘HT_caps_handler’:
drivers/staging/rtl8188eu/core/rtw_wlan_util.c:665:65: warning: array subscript 2 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds]
665 | if ((pmlmeinfo->HT_caps.ampdu_params_info & 0x3) > (pIE->data[i] & 0x3))
