Subject: [RFC v1] opp: add config option for debug
Date: Wed, 4 May 2022 19:48:23 +0200 [thread overview]
Message-ID: <20220504174823.156709-1-linux@fw-web.de> (raw)
From: Frank Wunderlich <frank-w@public-files.de>
Currently OPP debug is enabled by DEBUG_DRIVER option. This is generic
driver debug and opp floods serial console. This is annoying if opp is
not needed so give it an additional config-key.
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
