Hi Mauro, Here is a fix to the documentation warning. LIRC_CAN_SEND_SCANCODE was introduced in v4.16 to signify that kernel IR encoders could be used for IR Tx; this lirc feature bit was found to trip up the lirc daemon, so it was removed again but not from the lirc header. See https://git.linuxtv.org/v4l-utils.git/tree/utils/ir-ctl/ir-ctl.c#n763 how IR Tx using scancodes can be done. Thanks Sean The following changes since commit 7dbdd16a79a9d27d7dca0a49029fc8966dcfecc5: media: vb2: Makefile: place vb2-trace together with vb2-core (2018-02-26 11:39:04 -0500) are available in the Git repository at: git://linuxtv.org/syoung/media_tree.git for-v4.16d for you to fetch changes up to 1ddde79437bae627a7b0cadde6b88c544cbca285: media: rc: lirc does not use LIRC_CAN_SEND_SCANCODE feature (2018-02-28 12:07:48 +0000) ---------------------------------------------------------------- Sean Young (1): media: rc: lirc does not use LIRC_CAN_SEND_SCANCODE feature include/uapi/linux/lirc.h | 1 - 1 file changed, 1 deletion(-)
