2015-12-16drm/i915: refactor VBT validationJani Nikula3-36/+43
Make the validation function a boolean operating on a buffer of given size, removing the extra pointer dances.

2015-12-16drm/i915/bios: move debug logging about VBT source to intel_parse_bios()Jani Nikula1-7/+11
The decision about which source will be used for VBT is done in intel_parse_bios(), not in the VBT validation function. Make the VBT validation function strictly about validation, and move the debug logging to where it logically belongs. Also split the logging about where the valid VBT was found and what the signature is. This will make even more sense in the future when the validation for ACPI OpRegion based VBT takes place at OpRegion setup time. v2: Split logging about VBT signature and BDB version.

2015-12-15drm: use dev_name as default unique name in drm_dev_alloc()Nicolas Iooss7-16/+9
The following code pattern exists in some DRM drivers: ddev = drm_dev_alloc(&driver, parent_dev); drm_dev_set_unique(ddev, dev_name(parent_dev)); (Sometimes dev_name(ddev->dev) is used, which is the same.) As suggested in http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html, the unique name of a new DRM device can be set as dev_name(parent_dev) when parent_dev is not NULL (vgem is a special case).

2015-12-15drm: make drm_dev_set_unique() not use a format stringNicolas Iooss3-13/+8
drm_dev_set_unique() uses a format string to define the unique name of a device. This feature is not used as currently all the calls to this function either use "%s" as a format string or directly use dev_name(). Even though this second kind of call does not introduce security problems, because there cannot be "%" characters in dev_name() results, gcc issues a warning when building with -Wformat-security flag ("warning: format string is not a string literal (potentially insecure)"). This warning is useful to find real bugs like the one fixed by commit 3958b79266b1 ("configfs: fix kernel infoleak through user-controlled format string"). False positives which do not bring an extra value make the work of finding real bugs harder. Therefore remove the format-string feature from drm_dev_set_unique().

2015-12-15drm: Don't overwrite UNVERFIED mode status to OKVille Syrjälä1-1/+2
The way the mode probing works is this: 1. All modes currently on the mode list are marked as UNVERIFIED 2. New modes are on the probed_modes list (they start with status OK) 3. Modes are moved from the probed_modes list to the actual mode list. If a mode already on the mode list is deemed to match one of the probed modes, the duplicate is dropped and the mode status updated to OK. After this the probed_modes list will be empty. 4. All modes on the mode list are verified to not violate any constraints. Any that do are marked as such. 5. Any mode left with a non-OK status is pruned from the list, with an appropriate debug message. What all this means is that any mode on the original list that didn't have a duplicate on the probed_modes list, should be left with status UNVERFIED (or previously could have been left with some other status, but never OK). I broke that in commit 05acaec334fc ("drm: Reorganize probed mode validation") by always assigning something to the mode->status during the validation step. So any mode from the old list that still passed the validation would be left on the list with status OK in the end. Fix this by not doing the basic mode validation unless the mode already has status OK (meaning it came from the probed_modes list, or at least a duplicate of it was on that list). This way we will correctly prune away any mode from the old mode list that didn't appear on the probed_modes list.
