clk: qcom: clk-alpha-pll: Do not use random stack value for recalc rate

Browse source

[ Upstream commit 7a243e1b81 ]

If regmap_read() fails, random stack value was used in calculating new
frequency in recalc_rate() callbacks.  Such failure is really not
expected as these are all MMIO reads, however code should be here
correct and bail out.  This also avoids possible warning on
uninitialized value.
