Subject: [PATCH][next] drm/vmwgfx: Replace one-element array with
flexible-array member
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct vmw_view.
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].
This results in no differences in binary output.
