Subject: [PATCH 0/2] mfd: freeze delayed I/O work during suspend
Date: Fri, 16 Oct 2026 18:05:01 +0800 [thread overview]
Message-ID: <20261016100503.2581955-1-yaojiale02@163.com> (raw)
The SI476x polling callback and TPS65010 event worker issue I2C transfers
from delayed work. Their current workqueues remain active while devices are
being suspended, allowing pending callbacks to reach an already suspended
I2C adapter.
Move both callbacks to freezable workqueues. Preserve the TPS65010 worker's
power-efficient property by using system_freezable_power_efficient_wq.
Each patch is independent and can be applied separately.
