SubjectPotential uninitialized variable "reg" in clk: axi-clkgen
Hi All:

Inside function axi_clkgen_recalc_rate(), variable "reg" could be
uninitialized if axi_clkgen_mmcm_read() fails. However, "reg" is used
to decide the control flow later in the if statement, which is
potentially unsafe.

The patch for this case is not easy since the error return is not an
acceptable return value for axi_clkgen_recalc_rate().

Kind Regards,
