Subject: [PATCH AUTOSEL 6.12 037/486] thermal/drivers/mediatek/lvts: Start sensor interrupts disabled

From: Nícolas F. R. A. Prado <nfraprado@...labora.com>

[ Upstream commit 2738fb3ec6838a10d2c4ce65cefdb3b90b11bd61 ]

Interrupts are enabled per sensor in lvts_update_irq_mask() as needed,
there's no point in enabling all of them during initialization. Change
the MONINT register initial value so all sensor interrupts start
disabled.
