[PATCH 5.10 06/71] mISDN: Remove obsolete PIPELINE_DEBUG debugging information

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zhen Lei <thunder.leizhen@xxxxxxxxxx>

[ 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.
