Hi @lguohan
as described in this PR description:

Patchset contians 'mlxsw: i2c: Add device info log', adding info log
to probe() routine to report firmware setting in 'dmesg'.
This is not upstream commit, but this code has been exist in Sonic from
day one and used for debug purposes.

this log is very useful for the issue debug, so we want to keep it although it's not in the upstream, of course, need your approval.

[liat-grozovik]

@volodymyrsamotiy lets please divide the patch to 2: 1 fully aligned to upstream code, 1 with the extra patch which is not upstream and for debug purposes.

[liat-grozovik]

@lguohan now it should be aligned to only upstream code. Please check

[liat-grozovik]

@lguohan kindly please check if this can be merged. we have broken image on master and this fix is a must.
