+Subject: [PATCH 15/48] printk: nbcon: Do not rely on proxy headers
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.8/older/patches-6.8.2-rt11.tar.xz
+
+The headers kernel.h, serial_core.h, and console.h allow for the
+definitions of many types and functions from other headers.
+Rather than relying on these as proxy headers, explicitly
+include all headers providing needed definitions. Also sort the
+list alphabetically to be able to easily detect duplicates.
+
+Suggested-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
