They don't have a static in front of them, but they still have static
storage duration.

I fail to see how. Members not listed in the { initializer-list } are
implicitly initialized as if they were static objects, so flags should
already be zero.

(I assumed this patch is based on Shawn's imx-clk-5.5 tag)                                     

Cheers
Ahmad
