Subject: [PATCH] cxl/region: fix format string for resource_size_t
Date: Thu, 4 Dec 2025 10:52:26 +0100 [thread overview]
Message-ID: <20251204095237.1032528-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The size of this type is architecture specific, and the recommended
way to print it portably is through the custom %pap format string.
Fixes: d6602e25819d ("cxl/region: Add support to indicate region has extended linear cache")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
