Subject: [PATCH AUTOSEL 5.7 184/388] remoteproc/mediatek: fix invalid use of sizeof in scp_ipi_init()
From: Wei Yongjun <weiyongjun1@...wei.com>
[ Upstream commit 8096f80a5c09b716be207eb042c4e40d6cdefbd2 ]
sizeof() when applied to a pointer typed expression gives the
size of the pointer, not that of the pointed data.
