[PATCH 0/3] regulator: handle regulator late cleanup race with PM suspend

Posted by Joy Zou 1 week, 2 days ago

The regulator_init_complete_work fires ~30s after boot to disable
unused regulators via I2C. When this work races with PM suspend, the
I2C adapter may already be suspended, causing a -ESHUTDOWN warning
dump.

This series addresses the race and adds proper suspend power
management for unused LDO regulators.
