From: Benjamin Gray <bgray@linux.ibm.com> stable inclusion from stable-v6.6.2 commit ad0c8f4937327ba10ff71542a4d4994e75f9abf1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit ff7a60ab1e065257a0e467c13b519f4debcd7fcf ] Sparse reports a size mismatch in the endian swap. The Opal implementation[1] passes the value as a __be64, and the receiving variable out_qsize is a u64, so the use of be32_to_cpu() appears to be an error.
