Regular krealloc() obviously can't work with managed memory. This series
implements devm_krealloc() and adds the first user with hope that this
helper will be adopted by other drivers currently using non-managed
krealloc().

Some additional changes to the code modified by main patches are included.

v1 -> v2:
- remove leftover call to hwmon_device_unregister() from pmbus_core.c
- add a patch extending devm_kmalloc() to handle zero size case
- use WARN_ON() instead of WARN_ONCE() in devm_krealloc() when passed
  a pointer to non-managed memory
- correctly handle the case when devm_krealloc() is passed a pointer to
  memory in .rodata (potentially returned by devm_kstrdup_const())
- correctly handle ZERO_SIZE_PTR passed as the ptr argument in devm_krealloc()

Bartosz Golaszewski (6):
  devres: remove stray space from devm_kmalloc() definition
  devres: move the size check from alloc_dr() into a separate function
  device: remove 'extern' attribute from function prototypes in device.h
  devres: handle zero size in devm_kmalloc()
  devres: provide devm_krealloc()
  hwmon: pmbus: use more devres helpers
