[PATCH AUTOSEL 5.4 4/5] ACPI PPTT: Fix coding mistakes in a couple of sizeof() calls

[PATCH AUTOSEL 5.4 4/5] ACPI PPTT: Fix coding mistakes in a couple of sizeof() calls

[Sasha Levin]

From: Jean-Marc Eurin <jmeurin@google.com>

[ Upstream commit 7ab4f0e37a0f4207e742a8de69be03984db6ebf0 ]

The end of table checks should be done with the structure size,
but 2 of the 3 similar calls use the pointer size.
