Subject: [driver core] e2ae9bcc4a: unixbench.score -2.2% regression

Greeting,

FYI, we noticed a -2.2% regression of unixbench.score due to commit:


commit: e2ae9bcc4aaacda04edb75c4eea93384719efaa5 ("driver core: Add support for linking devices during device addition")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master


in testcase: unixbench
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:

	runtime: 300s
	nr_task: 1
	test: syscall
	cpufreq_governor: performance
	ucode: 0x5002f01

test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench

In addition to that, the commit also has significant impact on the following tests:


If you fix the issue, kindly add following tag
