Subject: [PATCH][next] drm/vmwgfx: Use struct_size() helper
Date: Wed, 17 Jun 2020 16:51:44 -0500 [thread overview]
Message-ID: <20200617215144.GA15547@embeddedor> (raw)
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
This code was detected with the help of Coccinelle and, audited and
fixed manually.
