Hi guys,

in kernel 2.6.30,  struct device, there is no member bus_id any more.
but in the drivers for the older version 2.6.29 for example, this
bus_id is still used.

I found a patch


which can get rid of the bus_id.

after I check the kernel source, I found that in the it seems
that this patch is already applied.

does this mean we can just directly delete the bus_id used in the
drivers for the older version kernel?


Best regards,
