Hey Younian, There seems to be a problem in the keymap you provided for inclusion in the kernel. In drivers/media/rc/keymaps/rc-hisi-poplar.c, 2 keys are triggered by the same keycode: 27 ↦ { 0x0000b2c5, KEY_DELETE},• 34 ↦ { 0x0000b2c5, KEY_BACK},• Could you please check what the correct values are for both of those keys? Thanks!
