Subject: [PATCH 5.10 06/71] mISDN: Remove obsolete PIPELINE_DEBUG debugging information
From: Zhen Lei <thunder.leizhen@...wei.com>
[ Upstream commit 2682ea324b000709dafec7e9210caa5189377c45 ]
As Leon Romanovsky's tips:
The definition of macro PIPELINE_DEBUG is commented more than 10 years ago
and can be seen as a dead code that should be removed.
