Subject: [PATCH] wimax/i2400m: Remove VLAIS

From: Behan Webster <behanw@...verseincode.com>

Convert Variable Length Array in Struct (VLAIS) to valid C by converting
local struct definition to use a flexible array. The structure is only
used to define a cast of a buffer so the size of the struct is not used
to allocate storage.
