Subject: [PATCH][next] media: dvb-usb: m920x: make read-only arrays static const
Date: Wed, 30 Nov 2022 18:04:58 +0000 [thread overview]
Message-ID: <20221130180458.1580847-1-colin.i.king@gmail.com> (raw)
Don't populate the arrays on the stack, instead make them static
const. Also makes the object code smaller.
