Hmm... This makes me even more confused since your device AMDI0010 
should not even use the access semaphore.

So linux-next works if you run a commit before it or revert these three 
patches? (commit 2f571a725434 ("i2c: designware: Fix lock probe call 
order in dw_i2c_plat_probe()") doesn't revert without reverting two 
other related commits after it)
