[PATCH] platform/x86: int3472/discrete: Drop a forward declaration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



By swapping the definition of skl_int3472_discrete_remove() and
skl_int3472_discrete_probe() the forward declaration of the former can
be dropped. This is a good thing as it removes code duplication.

Hello,

I didn't check in detail, but in my experience calling the remove
function in the error path of the probe function is prone to cleanup
errors. I didn't spot anything after a quick glance, but let me point
out this is unstable. E.g. in an error path of
skl_int3472_register_clock() the function is left with
int3472->clock.clk pointing to an unregistered clk and int3472->clock.cl
== NULL. Someone modifying the return function must be well aware of
that.

Best regards
Uwe
