stable inclusion from stable-v6.6.3 commit 32121a75b4d3f53445ad22a6eabc408be71c62b3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 7b1c6263eaf4fd64ffe1cafdc504a42ee4bfbb33 upstream.
It's only valid on Intel systems with the Intel VSEC. Use dev_is_removable() instead. This should do the right thing regardless of the platform.
