The new pxa2xx_determine_rate() function seems lacking in a few
regards:
- For an exact match or no match at all, the rate is uninitialized
as reported by gcc -Wmaybe-unintialized:
drivers/clk/pxa/clk-pxa.c: In function 'pxa2xx_determine_rate':
drivers/clk/pxa/clk-pxa.c:243:5: error: 'rate' may be used uninitialized in this function
- If we get a non-exact match, the req->rate output is never set
to the actual rate but remains at the requested rate.
- We should not attempt to print a rate if none could be found
This rewrites the logic accordingly.
