Subject: [PATCH 01/32] devtools/cocci: prefer structure assignment over memcpy
Date: Sat,  8 Feb 2025 12:21:53 -0800	[thread overview]
Message-ID: <20250208203142.242284-2-stephen@networkplumber.org> (raw)
In-Reply-To: <20250208203142.242284-1-stephen@networkplumber.org>

Prefer using simple structure assignment instead of memcpy.
Using a structure assignment preserves type information and
compiler checks types already.
