Why? What's the reason why you want to change this? The commit log
should always describe that.

> Tested-on: Qualcomm WCN6855

This is not correct format:

https://wireless.wiki.kernel.org/en/users/drivers/ath11k/submittingpatches#tested-on_tag

> Reported-by: kernel test robot <lkp@intel.com>
> Closes: https://lore.kernel.org/oe-kbuild-all/202306141105.c1e82Q0y-lkp@intel.com/

The robot only reported problems with your patch, it didn't report the
original problem. So you should remove these two lines.

> Signed-off-by: Arowa Suliman <arowa@google.com>

From and s-o-b have different email addresses.

Also this seems to a second version of your patch so you should have
marked it as v2 and include a changelog what changed from v1.

Please read our documentation from the wiki link below how to submit
patches.
