Hi Andrew,

The function dev_read_u32_default does not return an error and the
variable 'val' is unsigned so testing for >= 0 will always be true. It
looks like the code was attempting to return -1 if xtal-load-pf was not
present but that cannot work. Instead use dev_read_u32 which returns an
error code separately from writing the value into the passed pointer.
This issue was found by Smatch.
Fixes: 260777fc2333 ("clk: cdce9xx: add support for cdce9xx clock
synthesizer")
I believe? This should also add the original commit author in Cc which
may have more info on what was actually intended (but that was 6 years
ago already, so maybe they don't remember :) )
