[ 6.476367] WARNING: CPU: 9 PID: 567 at /build/linux-oem-osp1-bkWHJC/linux-oem-osp1-5.0.0/drivers/i2c/i2c-core-base.c:1322 i2c_add_numbered_adapter+0x81/0x90 [Fix] The 2 commits from v5.1-rc1 fix this issue. cd86d1403bb4 i2c: i2c-designware-platdrv: Always use a dynamic adapter number 77f3381a83c2 i2c: i2c-designware-platdrv: Cleanup setting of the adapter number [Test] Verified on Dell machine which had this issue. [Regression Potential] Low, the 2 commits make it always use dynamic adapter-numbers which does not make any difference in most cases and in the one case where it does make a difference the behavior change is desirable because the old behavior caused an oops.
