I've committed this patch.

Is there going to be another gdb-5.3.x release? If so, I'd like to
commit this to the branch.

    * gdb/avr-tdep.c (avr_io_reg_read_command): Fix to handle case when the
    number of io registers reported by remote target is not a multiple of
    step.

You're free to commit it to the branch (but it is very unlikely that 
there will be another release from the 5.3.x branch).
