Subject: [PATCH] iommu/riscv: Fixup compile warning
Date: Thu,  2 Jan 2025 21:46:16 -0500	[thread overview]
Message-ID: <20250103024616.3359159-1-guoren@kernel.org> (raw)

From: Guo Ren <guoren@linux.alibaba.com>

When __BITS_PER_LONG == 32, size_t is defined as unsigned int rather
than unsigned long. Therefore, we should use size_t to avoid
type-checking errors.

Fixes: 488ffbf18171 ("iommu/riscv: Paging domain support")
