Subject: [PATCH] firmware/psci: psci_checker: fix application of sizeof to pointer
Date: Tue, 24 Nov 2020 08:58:45 +0800 [thread overview]
Message-ID: <1606179525-63938-1-git-send-email-tiantao6@hisilicon.com> (raw)
sizeof when applied to a pointer typed expression gives the size of
the pointer.
The proper fix in this particular case is to code sizeof(*cpu_groups)
instead of sizeof(cpu_groups).
This issue was detected with the help of Coccinelle.
