by Zheng Zengkai 27 Mar '22

27 Mar '22

From: Yun Xu <xuyun(a)ramaxel.com> Ramaxel inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4ZR0O CVE: NA ------------------------------------ There are some issues of the driver that cannot be fixed now. The driver is not good enough for the LTS quality requirements of openEuler，so remove it.
