Subject: verification/dot2k: Remove __buff_to_string()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=612934e99b562c959ea5fc4c3adc75248b17b818;p=thirdparty%2Fkernel%2Flinux.git

verification/dot2k: Remove __buff_to_string()

str.join() can do what __buff_to_string() does. Therefore replace
__buff_to_string() to make the scripts more pythonic.
