CVE-2024-35796: debian linux Null Dereference — Fix

Description

In the Linux kernel, the following vulnerability has been resolved: net: ll_temac: platform_get_resource replaced by wrong function The function platform_get_resource was replaced with devm_platform_ioremap_resource_byname and is called using 0 as name.
