linux-next: build warning after merge of the clk tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi all,

After merging the clk tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/clk/bcm/clk-bcm2835.c: In function 'bcm2835_clock_determine_rate':
drivers/clk/bcm/clk-bcm2835.c:1069:18: warning: 'best_rate' may be used uninitialized in this function [-Wmaybe-uninitialized]
  *prate = curdiv * best_rate;
                  ^
drivers/clk/bcm/clk-bcm2835.c:1032:16: note: 'best_rate' was declared here
  unsigned long best_rate;
                ^

Introduced by commit

  155e8b3b0ee3 ("clk: bcm: Support rate change propagation on bcm2835 clocks")
