Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/1415 fix logging: redirection to DLGLOBAL for invalid categories For out-of-bounds logging categories, redirect to the proper DLGLOBAL array index instead of returning -1. Adjust test expectation which shows that the bugs tested for are fixed. Note: there are separate bounds checking problems, left for another patch.
