Subject: [PATCH v2] media: dvb: cleanup dead DVB_USB code in Kconfig
Date: Tue, 31 Mar 2026 16:32:30 +0100 [thread overview]
Message-ID: <20260331153230.15871-1-julianbraha@gmail.com> (raw)
There is already an 'if DVB_USB' condition wrapping most config
options, making the 'depends on' statement for each a duplicate
dependency (dead code).
Additionally, we can move the 'if DVB_USB' condition up to include
the DVB_USB_DEBUG config option, and also remove its specific
'depends on' statement.
This dead code was found by kconfirm, a static analysis tool for Kconfig.
