Which static checker?  I tried smatch and it only finds one:

arch/x86/kernel/cpu/resctrl/rdtgroup.c:3129 mkdir_mondata_subdir() error: uninitialized symbol 'ret'.

Which is a false positive (but I don't fault smatch for not understanding the relationship
between the two "if" blocks in this function.
