This is consistent with trying to access a filename that not exist
within a directory which is a good analogy here. The main reason for the
change is that it is easy to confuse the error code of EBADF as an
performing an ioctl on an invalid file descriptor (rather than an
unknown object).

Change the interface to expect a PTR_ERR specifing the real error code

Smatch complained that the ERR_PTR from hwmon_device_register() wasn't
handled.  I added some error handling in radeon_hwmon_init() to silence
the warning.

Unfortunately errors from radeon_pm_init() aren't handled so this
doesn't really make a difference beyond silencing the warning.

Also I changed DRM_ERROR() to dev_err() which is the new preferred
method.

router objects are found on systems that use a mux to control
ddc line to connector routing or to control the actual clock and data
routing from the chip to the connectors.  This patch implements ddc line

Previously we added i2c buses as needed when enumerating connectors
power management, etc.  This only exposed the actual buses used and
could have lead to the same buse getting created more than once if
one buses was used for more than one purpose.  This patch sets up
all i2c buses on the card in one place and users of the buses just
point back to the one instance.

- buffer offsets in the base regs are 256b aligned so
shift properly when comparing, fixed by Andre Maasikas
- mipmap size was calculated wrong when nlevel=0
- texture bo offsets were used after the bo base address was added
- vertex resource size register is size - 1, not size

(For some reason I thought that went in ages ago ...)

This fixes support for PCI domains in what should hopefully be a backward
compatible way along with a change to libdrm.

When the interface version is set to 1.4, we assume userspace understands
domains and the world is at peace. We thus pass proper domain numbers
instead of 0 to userspace.

The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
ignoring domains in the later case (well, except on alpha of course)

sil164 and friends are the most common, usually they just need to be
poked once because a fixed configuration is enough for any modes and
clocks, so they worked without this patch if the BIOS had done a good
job on POST. Display couldn't survive a suspend/resume cycle though.
Unfortunately, BIOS scripts are useless here.
