This isn’t a proper fix, but there’s some bad detection of RHEL 9.5 which is causing the issue.

If you edit line 101 of driver/2.6.27/include/linux_ver_fix.h to #define IS_RHEL_9_5 0 you will be able to build.

The full block is below. The error is due to the IS_RHEL_9_5 definition is being added on non RHEL OS’s like Debian.

#ifndef TTY_MAGIC
#define IS_RHEL_9_5 0
#else
#define IS_RHEL_9_5 0
#endif
