Re: [PATCH net v2 2/2] ax25: fix potential reference counting leak in ax25_addr_ax25dev

How do you think about to append parentheses to the function name
in the summary phrase?

Would you find the following change description a bit nicer?

   The reference counter of the object “ax25_dev” can be increased multiple times
   in ax25_addr_ax25dev(). This will cause a memory leak so far.

   Thus move a needed function call behind a for loop
   and increase the reference counter only when the local variable “res”
   is not a null pointer.

Would you like to omit curly brackets in the affected function implementation?
