Subject: firmware/psci: fix application of sizeof to pointer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4a3ef4d6d33023e2d7f03bed8d2f2edcebf8d94d;p=linux.git

firmware/psci: fix application of sizeof to pointer

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.
