From 0c119682cef99e25e99fc23018ef28c3af461c95 Mon Sep 17 00:00:00 2001 From: Benjamin Hipple Date: Thu, 16 Aug 2018 01:52:30 +0000 Subject: p7zip: vendor debian patches A few months ago I moved these patches to the new debian alsa instance [1], but it looks like their `sha256`s on the tag at the remote have changed again. It doesn't appear that debian's source remote is stable in the way we need it to be; let's just vendor the patches to avoid future issues.
