From 4e56d0a9f9c5612c724299136c8ef55bc436419b Mon Sep 17 00:00:00 2001 From: Oleksii Kurochko Date: Mon, 9 Sep 2024 13:42:57 +0200 Subject: [PATCH] xen/riscv: fix type mismatch in read_atomic_size() Correct a typo in read_atomic_size() where a 64-bit result was incorrectly cast to a `uint32_t` instead of `uint64_t` in the case of 8-byte reads.
