Subject: [PATCH v6 3/3] dm: verity-loadpin: Use CONFIG_SECURITY_LOADPIN_VERITY for conditional compilation
Date: Mon, 23 May 2022 14:14:00 -0700	[thread overview]
Message-ID: <20220523141325.v6.3.I5aca2dcc3b06de4bf53696cd21329dce8272b8aa@changeid> (raw)
In-Reply-To: <20220523211400.290537-1-mka@chromium.org>

The verity glue for LoadPin is only needed when CONFIG_SECURITY_LOADPIN_VERITY
is set, use this option for conditional compilation instead of the combo of
CONFIG_DM_VERITY and CONFIG_SECURITY_LOADPIN.
