Hi Christophe,

Thanks for your suggestions. However, both clk_get_rate and clk_prepare_enable
will return 0 if i2c->clk is NULL, so I think we may not need to take this issue
into account.

For some reaon, when I read:
> + rate = clk_get_rate(i2c->clk) / 1000;

I read "if i2c->clk is NULL, then the i2c pointer is NULL as well and is dereferenced".


sorry for the noise.
