Subject: [PATCH AUTOSEL 5.7 184/388] remoteproc/mediatek: fix invalid use of sizeof in scp_ipi_init()
Date: Wed, 17 Jun 2020 21:04:41 -0400 [thread overview]
Message-ID: <20200618010805.600873-184-sashal@kernel.org> (raw)
In-Reply-To: <20200618010805.600873-1-sashal@kernel.org>
From: Wei Yongjun <weiyongjun1@huawei.com>
[ Upstream commit 8096f80a5c09b716be207eb042c4e40d6cdefbd2 ]
sizeof() when applied to a pointer typed expression gives the
size of the pointer, not that of the pointed data.
Reviewed-by: Mathieu Poirier <mathieu.poirier@linaro.org>
Fixes: 63c13d61eafe ("remoteproc/mediatek: add SCP support for mt8183")
