This series

1. Splits device/devres.h for the users that are only interested in devres APIs.
   Original work by Andy Shevchenko:
   https://lore.kernel.org/r/20241203195340.855879-1-andriy.shevchenko@linux.intel.com

2. Introduces a more robust and cleaner devm_kmemdup_array() helper and uses it
   across drivers.

The idea behind embedding both work into a single series is to make the review
process easier and reduce conflicts while merging.

Current proposal is to merge initial patches with an immutable tag (volunteered
by Andy) for other subsystems to use. Feel free to share a better alternative.

v2: Use size_mul() for multiplication (Dmitry)
    Update commit message (Dmitry)

v3: Embed devres.h work by Andy
    Add more users of devm_kmemdup_array()
    Update tags and rebase

v4: Use IOMEM_ERR_PTR() to fix sparse warnings (Andy)
    Use source size and make it robust against type changes (Andy)

v5: Move IOMEM_ERR_PTR() to err.h (Andy)
    Reduce distribution to pinctrl/iio/input patches

Andy Shevchenko (2):
  driver core: Split devres APIs to device/devres.h
  iio: imu: st_lsm9ds0: Replace device.h with what is needed

Raag Jadav (10):
  err.h: move IOMEM_ERR_PTR() to err.h
  devres: Introduce devm_kmemdup_array()
  pinctrl: intel: copy communities using devm_kmemdup_array()
  pinctrl: baytrail: copy communities using devm_kmemdup_array()
  pinctrl: cherryview: use devm_kmemdup_array()
  pinctrl: tangier: use devm_kmemdup_array()
  pinctrl: pxa2xx: use devm_kmemdup_array()
  iio: adc: xilinx-xadc-core: use devm_kmemdup_array()
  input: sparse-keymap: use devm_kmemdup_array()
  input: ipaq-micro-keys: use devm_kmemdup_array()
