gpiod_get_value() can return negative values if an error occurs.
In several places this error code was ignored.
Ensure that errors codes are handled correctly throughout the CEC
pin framework and CEC pin drivers.
The return code of the cec_pin_ops read() callback had to be changed
from 'bool' to 'int', which mean the prototype of that callback in the
sun4i drm driver also had to be changed.

media: move CEC platform drivers to a separate directory2020-04-15T10:06:40ZMauro Carvalho Chehabmchehab+huawei@kernel.org2020-04-15T09:03:40Zurn:sha1:4be5e8648b0c287aefc6ac3f3a0b12c696054f43
As CEC support doesn't depend on MEDIA_SUPPORT, let's
place the platform drivers outside the media menu.
As a side effect, instead of depends on PCI, seco driver
can select it (and DMI).
