Subject: [PATCH 0/3] link regulator consumer with driver

From: pascal paillet <p.paillet@...com>

The goal of this patch-set is to ensure that a regulator driver is not suspended
before regulator consumer. Currently this is done by implementing suspend_late()
ops in the regulator driver but this is painful for an I2C controlled regulator.
Instead, the proposal is to add a device link between the driver and the consumer
at regulator core framework level.
To avoid storing the link pointer in the regulator core structure, we create
device_link_remove() function that use the same argument as device_link_add().

pascal paillet (3):
  driver core: Add device_link_remove function
  regulator: core: Link consumer with regulator driver
  regulator: core: Change suspend_late to suspend
