[PATCH] iommu/msm: simplify with dev_err_probe()

2022-02-06 Thread David Heidelberg
Use the dev_err_probe() helper to simplify error handling during probe.
This also handle scenario, when EDEFER is returned and useless error is
printed.

Fixes warnings as:
msm_iommu 750.iommu: could not get smmu_pclk
