question about drivers/phy/renesas/phy-rcar-gen2.c

[Julia Lawall]

Hello,

I was wondering whether phy-rcar-gen2.c would use dynamically allocated
device nodes?  If so, it looks like the following code could cause a
use-after-free, due to not incrementing th reference count:

        for_each_child_of_node(dev->of_node, np) {
                struct rcar_gen2_channel *channel = drv->channels + i;
                u32 channel_num;
                int error, n;

                channel->of_node = np;
                ...
        }

On the other hand, if the reference cound it incrememnted, preventing
memory leaks in the case where the probe function fails would entail some
complex rewriting of the code, so I thought it would be better to ask
first.

thanks,
julia
