Hi Kloudifold,

Good to include tags, but let's get them to the 'TAG' location.

The message you received from lkp is:
If you fix the issue, kindly add following tag where applicable
| Reported-by: kernel test robot <lkp@xxxxxxxxx>
| Link: https://lore.kernel.org/oe-kbuild-all/202303171454.sScrVVOh-lkp@xxxxxxxxx/

So, you take those 2 lines, and put them above your Signed-off-by:

Reported-by: kernel test robot <lkp@xxxxxxxxx>
Link: https://lore.kernel.org/oe-kbuild-all/202303171454.sScrVVOh-lkp@xxxxxxxxx/
Signed-off-by: Kloudifold <cloudifold.3125@xxxxxxxxx>

This is documented, but it's also a pattern that you can search for in
the lore archives to see how folks before you did it.

So - the above lines, starting with 'This v2 patch...' can be removed,
since you've stated it as a Change in v2.

wrt the other feedback about checkpatch failing - test you git commit
hook (per the first patch tutorial) and be sure you're doing a final
checkpatch on the formatted patch.

Keep at it Kloudifold :)
