+Subject: [PATCH] meson: Specify the maximum required libdrm in dri.pc
+
+When dealing with a regression in libdrm-2.4.101, I masked the package
+in Gentoo. In doing so, we discovered that Mesa's dri.pc specifies a
+version requirement in dri.pc for >= the version of libdrm Mesa was
+built against, thus preventing packages from being rebuilt with the
+older version of libdrm installed.
+
+Let's reduce this version requirement to the latest libdrm required by
+Mesa instead, since libdrm is backward compatible.
