Subject: [PATCH master 1/2] ARM: cpu: start: align uncompressed DTB size to 4 bytes
Date: Fri, 17 May 2024 08:22:24 +0200 [thread overview]
Message-ID: <20240517062225.3302101-1-a.fatoum@pengutronix.de> (raw)
KASAN reports that decompression exceeds the bounds of the allocation
and my DT size isn't 4-bytes aligned. Align the allocation size to fix
this.
