clk: qcom: Return error pointers for unimplemented clocks
Not all clocks are implemented but client drivers can still request them. Currently we will return a NULL pointer to them if the clock isn't implemented in software but NULL pointers are valid clock pointers. Return an error pointer so that driver's don't proceed without a clock they may actually need. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Mike Turquette <mturquette@linaro.org>
