* git://git.infradead.org/~dwmw2/ideapad-2.6:
Call acpi_video_register() in intel_opregion_init() failure path
ideapad: Only allow camera state to be set to 0 or 1
ideapad: Stop using global variables
Add Lenovo ideapad driver
|
|
If i915 opregion is present, the acpi_video driver doesn't register
itself immediately; it defers that until the i915 opregion code is done.
But if that *fails*, the acpi_video driver was never getting registered.
And thus I have no backlight support on my Lenovo IdeaPad S10-3.
Call acpi_video_register() on the failure path, and it works again.

When removing of the BKL the locking around lastclose() was rearranged
and resulted in the holding of the open_count spinlock over the call
into drm_lastclose(). The drivers were not ready for this path to be
atomic - it may indeed involve long waits to release old objects and
cleanup the GPU - and so we ended up scheduling whilst atomic.

v2: The spinlock is actually superfluous as access to open_count is
entirely serialised by drm_global_mutex and so can be dropped. The
count_lock spinlock instead appears to be used to protect access to
dev->buf_alloc and dev->buf_use.

Jesse's initial patch commit said:
"At panic time (i.e. when oops_in_progress is set) we should try a bit
harder to update the screen and make sure output gets to the VT, since
some drivers are capable of flipping back to it.
So make sure we try to unblank and update the display if called from a
panic context."
I've enhanced this to add a flag to the vc that console layer can set to
indicate they want this behaviour to occur. This also adds support to
fbcon for that flag and adds an fb flag for drivers to indicate they want
to use the support. It enables this for KMS drivers.

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).

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.

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.

(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)

Commit 991ea75c (drm: use workqueue instead of slow-work), which made
drm to use wq instead of slow-work, didn't account for the return
value difference between delayed_slow_work_enqueue() and
queue_delayed_work(). The former returns 0 on success and -errno on
failures while the latter never fails and only uses the return value
to indicate whether the work was already pending or not.
This misconversion triggered spurious error messages. Remove the now
unnecessary return value check and error message.
