+From: Arch Linux contributors
+Subject: [compiler-rt][sanitizer] Remove linux/scc.h
+
+linux/scc.h was dropped from the kernel UAPI headers and is no longer
+shipped by linux-api-headers >= 7.1, so building sanitizer_common fails
+with "fatal error: 'linux/scc.h' file not found".
+
+struct_scc_modem_sz and struct_scc_stat_sz are not referenced by the
+ioctl interceptors, so they can be removed along with the include.
+
+Backport of llvm/llvm-project commit 3dc4fd6dd ("[compiler-rt][sanitizer]
+Remove linux/scc.h", #194116), adjusted to apply on the ROCm fork, which
+predates the reindentation of that include block.
