hw/scsi/mptendian: Avoid taking address of fields in packed structs
Taking the address of a field in a packed struct is a bad idea, because it might not be actually aligned enough for that pointer type (and thus cause a crash on dereference on some host architectures). Newer versions of clang warn about this. Avoid the bug by not using the "modify in place" byte swapping functions. This patch was produced with the following simple spatch script: @@ expression E; @@ -le16_to_cpus(&E); +E = le16_to_cpu(E); @@ expression E; @@ -le32_to_cpus(&E); +E = le32_to_cpu(E); @@ expression E; @@ -le64_to_cpus(&E); +E = le64_to_cpu(E); @@ expression E; @@ -cpu_to_le16s(&E); +E = cpu_to_le16(E); @@ expression E; @@ -cpu_to_le32s(&E); +E = cpu_to_le32(E); @@ expression E; @@ -cpu_to_le64s(&E); +E = cpu_to_le64(E); followed by some minor tidying of overlong lines and bad indent.
