Subject: [PATCH][next] thermal: lvts: make some read-only arrays static const
Date: Tue, 17 Oct 2023 18:16:55 +0100 [thread overview]
Message-ID: <20231017171655.177096-1-colin.i.king@gmail.com> (raw)
Don't populate the read-only arrays on the stack, instead make them
static const. Make lvts_write_config parameters cmds and nr_cmds
const too.
