[PATCH] clk: imx: pll14xx: initialize flags to 0

[PATCH] clk: imx: pll14xx: initialize flags to 0

[Peng Fan]

From: Peng Fan <peng.fan@nxp.com>

init.flags is initialized with value from pll_clk->flags, however
imx_1443x_pll and imx_1416x_pll are not static structure, so flags
might be random value. So let's initialize flags as 0 now.

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

Yes. I am wrong.
