Subject: egl: Unhide functionality in _eglInitContext()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1456ed85f0ed8b9c9f0abd6bd389a089fa3824b2;p=mesa.git

egl: Unhide functionality in _eglInitContext()

_eglInitResource() was used to memset entire _EGLContext by
writing more than size of pointed target. This does work
as long as Resource is the first element in _EGLContext,
this patch fixes such dependency.
