Public bug reported:
On prior kernel 6.10, i get proper values, when i use i2cdetect -y 0,
whereas on 6.11, i get the following:
❯ i2cdetect -y 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- --
10: -- -- -- -- -- 15 -- -- -- -- -- -- -- -- -- --

30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- 49 -- 4b -- -- -- 4f
50: -- UU -- UU -- -- -- -- -- -- -- -- -- -- -- --
60: -- 61 -- 63 -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
The addresses 0x51 and 0x53 are not readable anymore, whereas on 6.10
they are. I tested this when rebooting the kernels. I am currently only
6.11, thus the output. I'll add the output from 6.10 on my next boot.
