Hi, Mark and Andi
While looking at next-20260910, I noticed that the merge commit:
commit 2edfbdfb8f9c5b2482232087a03fa1a6692b9e5b
Merge: 98d87b29bc8a7 61ddec70c9bcc

Merge branch 'rust-i2c-next' of https://github.com/ikrtn/rust-for-linux
# Conflicts:
# drivers/i2c/busses/i2c-imx-lpi2c.c
After this merge, I meet a regression on the i.MX8Q series starting from next-20260910
(next-20260909 was still fine).
The root cause is:
Change to lpi2c_imx_probe() from this patch[1] was replaced back with the old logic during the merge conflict resolution(2edfbdfb8f9c).
Could you help pick these missing codes back?
