Subject: [PATCH] crypto: hisilicon/qm: Change type of pasid to u32
Date: Thu, 25 Jun 2020 13:07:12 -0700	[thread overview]
Message-ID: <1593115632-31417-1-git-send-email-fenghua.yu@intel.com> (raw)

PASID is defined as "int" although it's a 20-bit value and shouldn't be
negative int. To be consistent with PASID type in iommu, define PASID
as "u32".

Suggested-by: Thomas Gleixner <tglx@linutronix.de>

PASID type will be changed consistently as u32:
