Subject: kdb: Remove unused KDB_FLAG_ONLY_DO_DUMP
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0f26d0e0a715556270d85b7946b99546a2f92888;p=linux-beck.git

kdb: Remove unused KDB_FLAG_ONLY_DO_DUMP

This code cleanup was missed in the original kdb merge, and this code
is simply not used at all.  The code that was previously used to set
the KDB_FLAG_ONLY_DO_DUMP was removed prior to the initial kdb merge.
