SubjectRe: [PATCH 2/2] leds: sunxi: New driver for the R329/D1 LED controller
Hi Samuel,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on pavel-linux-leds/for-next]
[also build test ERROR on next-20210903]
[cannot apply to robh/for-next sunxi/sunxi/for-next v5.14]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch]
