From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> stable inclusion from stable-5.10.52 commit b3aea76efe90d7676e6965fe2f017d7ffc128b37 bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- This reverts commit fcb041ca5c7787b096aafc899e45f93583e66cbd which is commit 0ecb51824e838372e01330752503ddf9c0430ef7 upstream. Turns out this was incomplete, as it is missing a dependancy, so drop it from the tree. Link: https://lore.kernel.org/r/CAJn8CcHHKSo7GF29Z1ufXJJpMUzn6+fdvwiqe9=JvgpcfvnbH...
