2016-02-05drm/dp/mst: deallocate payload on port destructionMykola Lysenko1-8/+83
This is needed to properly deallocate port payload after downstream branch get unplugged. In order to do this unplugged MST topology should be preserved, to find first alive port on path to unplugged MST topology, and send payload deallocation request to branch device of found port. For this mstb and port kref's are used in reversed order to track when port and branch memory could be freed. Added additional functions to find appropriate mstb as described above.

2016-02-05drm/dp/mst: move GUID storage from mgr, port to only mst branchHersen Wu2-51/+38
Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

2016-02-05drm/dp/mst: change MST detection schemeMykola Lysenko1-18/+19
1. Get edid for all connected MST displays, not only on logical ports, in the same thread as MST topology detection is done: There are displays that have branches inside w/o logical ports. So in case another SST display connected downstream system can end-up in situation when 3 DOWN requests sent: two for ‘remote i2c read’ and one for ‘enum path resources’, making slots full. 2. Call notification callback in one place in the end of topology discovery/update: This is done to reduce number of events sent to userspace in case complex topology discovery is going, adding multiple number of connectors; 3. Remove notification callback call from short pulse interrupt processing function: This is done in order not to block interrupt processing function, in case any MST request will be made from it. Notification will be send from topology discovery/update work item.

2016-02-05drm/dp/mst: Calculate MST PBN with 31.32 fixed pointHarry Wentland1-28/+39
Our PBN value overflows the 20 bits integer part of the 20.12 fixed point. We need to use 31.32 fixed point to avoid this. This happens with display clocks larger than 293122 (at 24 bpp), which we see with the Sharp (and similar) 4k tiled displays.

2016-02-05drm: Add drm_fixp_from_fraction and drm_fixp2int_ceilHarry Wentland1-2/+51
drm_fixp_from_fraction allows us to create a fixed point directly from a fraction, rather than creating fixed point values and dividing later. This avoids overflow of our 64 bit value for large numbers. drm_fixp2int_ceil allows us to return the ceiling of our fixed point value.

2016-02-04crush: ensure bucket id is valid before indexing buckets arrayIlya Dryomov1-2/+10
We were indexing the buckets array without verifying the index was within the [0,max_buckets) range. This could happen because a multistep rule does not have enough buckets and has CRUSH_ITEM_NONE for an intermediate result, which would feed in CRUSH_ITEM_NONE and make us crash.

2016-02-04ALSA: timer: Fix leftover link at closingTakashi Iwai1-2/+2
In ALSA timer core, the active timer instance is managed in active_list linked list. Each element is added / removed dynamically at timer start, stop and in timer interrupt. The problem is that snd_timer_interrupt() has a thinko and leaves the element in active_list when it's the last opened element. This eventually leads to list corruption or use-after-free error. This hasn't been revealed because we used to delete the list forcibly in snd_timer_stop() in the past. However, the recent fix avoids the double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link corruption due to double start or stop]), and this leak hits reality. This patch fixes the link management in snd_timer_interrupt(). Now it simply unlinks no matter which stream is.

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab1-1/+1
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil3-54/+46
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed.

The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning.

2016-02-03PM: Avoid false-positive warnings in dev_pm_domain_set()Rafael J. Wysocki1-1/+1
There is a WARN_ON() in dev_pm_domain_set() that triggers on attempts to set the pm_domain pointer for devices with a driver bound. However, that WARN_ON() triggers on attempts to clear the pointer too and the test it uses is based on checking the device's p->knode_driver pointer which still is set when the device bus type's/driver's ->remove callback has been executed. This leads to false-positive warnings when bus type code calls dev_pm_domain_set() to clear the pm_domain pointer after invoking the driver's ->remove() callback. To avoid those false-positives, make dev_pm_domain_set() check if the pointer passed to it is NULL and skip the warning in that case.

2016-02-03ipmi: put acpi.h with the other headersTony Camuso1-2/+1
Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is unnecessary, since it has its own conditional compile for CONFIG_ACPI. Commit 0fbcf4af7c83 ("ipmi: Convert the IPMI SI ACPI handling to a platform device") exposed this as a problem for platforms that do not support ACPI when it introduced a call to ACPI_PTR() macro outside of the CONFIG_ACPI conditional compile. This would have been perfectly acceptable if acpi.h were not conditionally excluded for the non-acpi platform, because the conditional compile within acpi.h defines ACPI_PTR() to return NULL when compiled for non acpi platforms.
