Subject: drm/amdkfd: Replace zero-length array with flexible-array member
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d5c831566d34924f62082f8b675d35c078f9b45c;p=linux.git

drm/amdkfd: 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" for these cases. The older
style of one-element or zero-length arrays should no longer be used.
