Subject: [PATCH RFC v3 3/7] mfd: ls2kbmc: Redraw using exported functions
Date: Fri, 10 Jul 2026 01:24:19 +0800	[thread overview]
Message-ID: <20260710-ls2kbmc-mod-v3-3-ef718636e78e@gmail.com> (raw)
In-Reply-To: <20260710-ls2kbmc-mod-v3-0-ef718636e78e@gmail.com>

From: Miao Wang <shankerwangmiao@gmail.com>

Use update_screen, i.e. redraw_screen() to trigger the redraw of the
current vt.

Fixes: d952bba3fbb5 ("mfd: ls2kbmc: Add Loongson-2K BMC reset function support")
