[Linux-stm32] [PATCH 3/4] ARM: dts: stm32: enable stmpe811 on stm32429-disco board

[Hua Dillon]

hi, alexandre torgue

so, if i add "---" below
 Signed-off-by: dillon min <dillon.minfei at gmail.com>
 in git commit process, with changes log after that.  the log will not show
in commit messages, but will exist in git patchs, just showing for
reviewers ?

i will try this tomorrow, resubmit it.

thanks for your help.

best regards

dillon
