Hi Vincent,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linus/master]
[also build test ERROR on bff6f1db91e330d7fba56f815cdbc412c75fe163 v5.10-rc3 next-20201113]
[If your patch is applied to the wrong git tree, kindly drop us a note.
Patch is applied to the wrong git tree. It is based on the testing
branch of linux-can-next:
https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/log/?h=testing
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch]
I did so (c.f. the base-commit and prerequisite-patch-id tags at the
bottom of the patch). While the base-commit was taken into account,
the prerequisite-patch-id tags seem to have been ignored.
FYI, I used the below command to generate the patch.
git format-patch --base=bff6f1db91e330d7fba56f815cdbc412c75fe163 -v6
-o patch/v6 HEAD~1
Hi Vincent,
Thanks for the feedback, we'll fix the problem asap.
Best Regards,
Rong Chen
Yours sincerely,
Vincent Mailhol
