From a2cfad8ecc28923db6f826c01359c768980085e7 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 24 May 2021 11:47:01 -0400 Subject: [PATCH] pylibfdt: Rework "avoid unused variable warning" lines Clang has -Wself-assign enabled by default under -Wall and so when building with -Werror we would get an error here. Inspired by Linux kernel git commit a21151b9d81a ("tools/build: tweak unused value workaround") make use of the fact that both Clang and GCC support casting to `void` as the method to note that something is intentionally unused.
