X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=aa125f313d8e7d04bf001175dadeabaf8723c00b;p=linux.git

firmware: google: vpd: Replace zero-length array with flexible-array member

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].
