…ASE_CODE RHEL 9 ships a 5.14 kernel but backports class_create(), vm_flags, device_find_child match, and devnode signatures, so LINUX_VERSION_CODE alone selected the wrong branch and mx_dma failed to build. Gate the four sites on RHEL_RELEASE_CODE >= 9.6 as well.

🤔 배경 및 동기 (Why)
RHEL 9(el9)은 5.14 커널에 mainline 6.x API를 backport해서 순수
LINUX_VERSION_CODE가드가 잘못된 분기를 선택 →mx_dmadkms 빌드가 실패합니다.📝 변경
class_create(1-arg),vm_flags_set,device_find_childmatch(const void*),devnode(const struct device*) 4개 가드에RHEL_RELEASE_CODE >= RHEL_RELEASE_VERSION(9, 6)를 병용mx_dma.h에RHEL_RELEASE_CODE스텁 추가 — 비-RHEL 환경 무영향✅ 테스트
