The SECO CEC driver never decremented the HDMI device refcount.
CEC drivers only need the HDMI device pointer as a key in the
notifier list, it never accesses the device, so there is no
need to keep a reference.

The actual value of the RC5 System Number (address) is stored in the
IR_READ_DATA common register masked with 0x1F00 so it have to be shifted
by 8 bits.

Fix build errors due to missing <linux/module.h> header file.
The header file is inserted first because module-related errors
begin showing up in <linux/acpi.h> (when CONFIG_ACPI is not set).

This struct should be static. Also, it is const, so declare it

Introduce support for Consumer-IR into seco-cec driver, as it shares the
same interrupt for receiving messages.
The device decodes RC5 signals only, defaults to hauppauge mapping.
It will spawn an input interface using the RC framework (like CEC
device).

This patch adds support to the CEC device implemented with a STM32
microcontroller in X86 SECO Boards, including UDOO X86.
The communication is achieved via Braswell integrated SMBus
(i2c-i801). The driver use direct access to the PCI addresses, due to
the limitations of the specific driver in presence of ACPI calls.
The basic functionalities are tested with success with cec-ctl and
cec-compliance.
Inspired by cros-ec-cec implementation, attaches to i915 driver
cec-notifier.
