stable inclusion from stable-v5.10.112 commit 2ad9d890d850db6c55ec2d9b5b3cbb7ca5178f3f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5HL0X
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit e6934e4048c91502efcb21da92b7ae37cd8fa741 ]
The DSA master might not have been probed yet in which case the probe of the felix switch fails with -EPROBE_DEFER: [ 4.435305] mscc_felix 0000:00:00.5: Failed to register DSA switch: -517
It is not an error. Use dev_err_probe() to demote this particular error to a debug message.
