x86/events/amd/iommu: Fix sizeof mismatch
[ Upstream commit 59d5396a4666195f89a67e118e9e627ddd6f53a1 ]
An incorrect sizeof is being used, struct attribute ** is not correct,
it should be struct attribute *. Note that since ** is the same size as
* this is not causing any issues. Improve this fix by using sizeof(*attrs)
as this allows us to not even reference the type of the pointer.
Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")
Fixes: 51686546304f ("x86/events/amd/iommu: Fix sysfs perf attribute groups")
