The dax_region resource conflict in alloc_dax_region() indicates a serious configuration problem — two subsystems (e.g. dax_hmem and dax_cxl) are attempting to register overlapping address ranges. This is not a transient or debug-level condition; it represents a genuine resource conflict that an administrator needs to be aware of. Promote the log level from dev_dbg() to dev_err() so that the conflict is visible by default without requiring dynamic debug to be enabled.
