Subject: [PATCH] media: dvb: dib0090: remove code guarded by nonexistent config options
Date: Sat, 13 Jun 2026 13:44:00 -0700 [thread overview]
Message-ID: <20260613204403.62664-1-enelsonmoore@gmail.com> (raw)
Some code in the dib0090 driver depends on CONFIG_BAND_LBAND or
CONFIG_BAND_SBAND, which have never been defined in the kernel.
Remove this dead code.
Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
