    SubjectRe: [PATCH v7 3/3] Input: Add TouchNetix axiom i2c touchscreen driver
    Hi Kamel,

    kernel test robot noticed the following build warnings:

    [auto build test WARNING on dtor-input/next]
    [also build test WARNING on dtor-input/for-linus robh/for-next krzk-dt/for-next linus/master v6.8-rc2 next-20240202]
    [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#_base_tree_information]
