HI All,
In the function_fs driver in 3.10 kernel, for every functionfs_bind
the next_string_id is incremented.
But on an unbind I could not see this getting decremented.
This counter is getting incremented and when it reaches 254, the USB
connection was failing consistently,
as there is a check in usb_string_ids_n (snippet below)
if (unlikely(n > 254 || (unsigned)next + n > 254))
return -ENODEV;
c->next_string_id += n;
We could see the next_string_id being made to 0, in composite_dev_cleanup,
but this path was not being taken in functionfs case.
Is similar change or a decrement of next_string_id required while we do
functionfs_unbind also?
Thanks and Regards
Anjana
