[PATCH -next] ACPI/IORT: Fix the error return code in iort_add_smmu_platform_device()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

The error return code PTR_ERR(pdev) is always 0 since pdev is
equal to 0 in this error handling case.
