[PATCH 5.10 020/575] firmware/psci: fix application of sizeof to pointer

[Greg Kroah-Hartman]

From: jing yangyang <cgel.zte@xxxxxxxxx>

commit 2ac5fb35cd520ab1851c9a4816c523b65276052f upstream.

sizeof when applied to a pointer typed expression gives the size of
the pointer.

./drivers/firmware/psci/psci_checker.c:158:41-47: ERROR application of sizeof to pointer

This issue was detected with the help of Coccinelle.

Fixes: 7401056de5f8 ("drivers/firmware: psci_checker: stash and use topology_core_cpumask for hotplug tests")
