Subject: [PATCH] thermal/drivers/mediatek/lvts: fix mt7987 thermal crash
Date: Mon, 9 Mar 2026 07:44:38 +0100 [thread overview]
Message-ID: <20260309064439.4296-1-linux@fw-web.de> (raw)
From: Frank Wunderlich <frank-w@public-files.de>
On mt7987 we see a crash due to missing ops entry.
[ 1.518540] Internal error: Oops: 0000000096000005 [#1] SMP
...
[ 1.564481] pc : lvts_get_temp+0x84/0xc4
[ 1.564492] lr : lvts_get_temp+0x60/0xc4
...
[ 1.620900] Call trace:
[ 1.631753] lvts_get_temp+0x84/0xc4 (P)
[ 1.645471] __thermal_zone_get_temp+0x24/0x11c
[ 1.656502] __thermal_zone_device_update+0x9c/0x52c
Add the new ops member added in 7.0-rc1 for mt7987 too.
Fixes: a4c40559499f ("thermal/drivers/mediatek/lvts: Add platform ops to support alternative conversion logic")
