## Overview

In the Linux kernel, the following vulnerability has been resolved:

regulator: core: use system_freezable_wq for init complete work

schedule_delayed_work() uses system_wq, which is non-freezable, allowing
regulator_init_complete_work to run concurrently with system suspend. This
work fires ~30s after boot to disable unused regulators via I2C. When it
races with PM suspend, the I2C adapter may already be suspended, triggering
a -ESHUTDOWN warning in __i2c_transfer():

  WARNING: ... at __i2c_transfer+0x36c/0x3c8
  Call trace:
   __i2c_transfer
   i2c_transfer
   regmap_i2c_write
   _regmap_update_bits
   regulator_disable_regmap
   _regulator_do_disable
   regulator_late_cleanup
   regulator_init_complete_work_function
   process_one_work

Switch to system_freezable_wq so the work is frozen before any device
is suspended, eliminating the race.
