Subject: [PATCH 3/4] irqchip/gic-v3-its: drop redundant initialization in mk_lpi_range
Date: Tue, 12 Mar 2019 18:33:48 +0100	[thread overview]
Message-ID: <20190312173350.4025-4-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20190312173350.4025-1-linux@rasmusvillemoes.dk>

There's no reason to ask kmalloc() to zero the allocation, since all
the fields get initialized immediately afterwards. Except that there's
also not any reason to initialize the ->entry member, since the
element gets added to the lpi_range_list immediately.
