Subject: clk: use uninitialized_var instead setting 'flags' to 0 directly.
X-Git-Tag: firefly_0821_release~176^2~3030^2~10

clk: use uninitialized_var instead setting 'flags' to 0 directly.

Setting 'flags' to zero will be certainly a misleading way to avoid
warning of 'flags' may be used uninitialized. uninitialized_var is
a correct way because the warning is a false possitive.
