Merge tag 'trace-fixes-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "A feature was added in 4.3 that allowed users to filter trace points on a tasks "comm" field. But this prevented filtering on a comm field that is within a trace event (like sched_migrate_task). When trying to filter on when a program migrated, this change prevented the filtering of the sched_migrate_task. To fix this, the event fields are examined first, and then the extra fields like "comm" and "cpu" are examined. Also, instead of testing to assign the comm filter function based on the field's name, the generic comm field is given a new filter type (FILTER_COMM). When this field is used to filter the type is checked. The same is done for the cpu filter field. Two new special filter types are added: "COMM" and "CPU". This allows users to still filter the tasks comm for events that have "comm" as one of their fields, in cases that users would like to filter sched_migrate_task on the comm of the task that called the event, and not the comm of the task that is being migrated" * tag 'trace-fixes-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not have 'comm' filter override event 'comm' field

Commit 9f616680 "tracing: Allow triggers to filter for CPU ids and process names" added a 'comm' filter that will filter events based on the current tasks struct 'comm'. But this now hides the ability to filter events that have a 'comm' field too. For example, sched_migrate_task trace event. That has a 'comm' field of the task to be migrated. echo 'comm == "bash"' > events/sched_migrate_task/filter will now filter all sched_migrate_task events for tasks named "bash" that migrates other tasks (in interrupt context), instead of seeing when "bash" itself gets migrated. This fix requires a couple of changes. 1) Change the look up order for filter predicates to look at the events fields before looking at the generic filters. 2) Instead of basing the filter function off of the "comm" name, have the generic "comm" filter have its own filter_type (FILTER_COMM). Test against the type instead of the name to assign the filter function. 3) Add a new "COMM" filter that works just like "comm" but will filter based on the current task, even if the trace event contains a "comm" field. Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU". Cc: stable@vger.kernel.org # v4.3+ Fixes: 9f616680 "tracing: Allow triggers to filter for CPU ids and process names" Reported-by:

Defer to register acomp eld notifier until hdmi audio driver is fully ready. After registering eld notifier, gfx driver can use this callback function to notify audio driver the monitor connection event. However this action may happen when audio driver is adding the pins or doing other initialization. This is not always safe, however. For example, using per_pin->lock before the lock is initialized. Let's register the eld notifier after the initialization is done. Signed-off-by:
