Subject: [PATCH 6.6 162/299] platform/x86: intel-vbtn: Stop calling "VBDL" from notify_handler
Date: Tue, 27 Feb 2024 14:24:33 +0100 [thread overview]
Message-ID: <20240227131631.070692170@linuxfoundation.org> (raw)
In-Reply-To: <20240227131625.847743063@linuxfoundation.org>
6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
commit 84c16d01ff219bc0a5dca5219db6b8b86a6854fb upstream.
Commit 14c200b7ca46 ("platform/x86: intel-vbtn: Fix missing
tablet-mode-switch events") causes 2 issues on the ThinkPad X1 Tablet Gen2:
1. The ThinkPad will wake up immediately from suspend
2. When put in tablet mode SW_TABLET_MODE reverts to 0 after about 1 second
Both these issues are caused by the "VBDL" ACPI method call added
at the end of the notify_handler.
And it never became entirely clear if this call is even necessary to fix
the issue of missing tablet-mode-switch events on the Dell Inspiron 7352.
Drop the "VBDL" ACPI method call again to fix the 2 issues this is
causing on the ThinkPad X1 Tablet Gen2.
