[PATCH v5 0/5] soc: qcom: ice: Fix race between qcom_ice_probe() and of_qcom_ice_get()

[Manivannan Sadhasivam via B4 Relay <devnull+manivannan.sadhasivam.oss.qualcomm.com@kernel.org>]

Hi,

This series fixes the race betwen qcom_ice_probe() and of_qcom_ice_get()
but synchronizing the two APIs and properly propagating the error codes to
clients.

Merge Strategy
==============

Due to dependency, all patches should go through Qcom SoC tree.

Changes in v5:
- Used Xarray instead of platform drvdata for passing the pointer since driver
  core frees drvdata on probe failure.
- Link to v4: https://lore.kernel.org/r/20260302-qcom-ice-fix-v4-0-0e65740a5dcc@oss.qualcomm.com

Changes in v4:
- For supporting multi-ice instances in a SoC, stored the err ptr in platform
  drvdata instead of in a global pointer.
- Link to v3: https://lore.kernel.org/r/20260223-qcom-ice-fix-v3-0-6ca5846329f7@oss.qualcomm.com

Changes in v3:
- Dropped the platform driver removal patch and used the ice_handle to pass
  error codes. This was done as I learned that we need to have the platform
  driver design going forward and also removing it introduces other issues.
- Link to v2: https://lore.kernel.org/r/20260210-qcom-ice-fix-v2-0-9c1ab5d6502c@oss.qualcomm.com

Changes in v2:

- Added MODULE_* macros back
- Removed spurious platform_device_put()
- Added patches to remove NULL return
