dev_read_u32_default() always returns something even when the property is missing. So, it is impossible to do nothing in the case. One solution is to use ofnode_read_u32() instead, but adding dev_read_u32() will be helpful. BTW, Linux has an equvalent function, device_property_read_u32(); it is clearer that it reads a property. I cannot understand the behavior of dev_read_u32() from its name. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |
