| H A D | resolver.c | 482137bf Wed May 16 23:19:51 CDT 2018 Frank Rowand <frank.rowand@sony.com> of: overlay: validate offset from property fixups
The smatch static checker marks the data in offset as untrusted,
leading it to warn:
drivers/of/resolver.c:125 update_usages_of_a_phandle_reference()
error: buffer underflow 'prop->value' 's32min-s32max'
Add check to verify that offset is within the property data.
