Subject: [PATCH] kernel.bbclass: add lz4 dependency and fix the call to lz4
Date: Fri,  3 Jul 2020 08:22:10 +0200	[thread overview]
Message-ID: <20200703062210.9471-1-timon.ulrich@kabelmail.de> (raw)

From: Timon Ulrich <t.ulrich@anapur.de>

If the initramfs image is type lz4, then a native lz4 is needed.

Additionally an output filename needs to be specified when calling lz4,
otherwise STDOUT will be used implicitly.
