+Subject: ALSA: hda: Drop useless WARN_ON()
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit a36c2638380c0a4676647a1f553b70b20d3ebce1 upstream.
+
+Since the commit 97cc2ed27e5a ("ALSA: hda - Fix yet another i915
+pointer leftover in error path") cleared hdac_acomp pointer, the
+WARN_ON() non-NULL check in snd_hdac_i915_register_notifier() may give
+a false-positive warning, as the function gets called no matter
+whether the component is registered or not. For fixing it, let's get
+rid of the spurious WARN_ON().
+

+

+
+commit 695b78b548d8a26288f041e907ff17758df9e1d5 upstream.
+
+AC'97 ops (register read / write) need SSI regmap and clock, so they have
+to be set after them.
+
+We also need to set these ops back to NULL if we fail the probe.

+
+commit 15f8c5f2415bfac73f33a14bcd83422bcbfb5298 upstream.
+
+Fix child-node lookup during probe, which ended up searching the whole
+device tree depth-first starting at the parent rather than just matching
+on its children.
+
+To make things worse, the parent codec node was also prematurely freed,
+while the child node was leaked.

+Subject: ring-buffer: Mask out the info bits when returning buffer page length
+
+From: Steven Rostedt (VMware) <rostedt@goodmis.org>
+
+commit 45d8b80c2ac5d21cd1e2954431fb676bc2b1e099 upstream.
+
+Two info bits were added to the "commit" part of the ring buffer data page
+when returned to be consumed. This was to inform the user space readers that
+events have been missed, and that the count may be stored at the end of the
+page.
+
+What wasn't handled, was the splice code that actually called a function to
+return the length of the data in order to zero out the rest of the page
+before sending it up to user space. These data bits were returned with the
+length making the value negative, and that negative value was not checked.
+It was compared to PAGE_SIZE, and only used if the size was less than
+PAGE_SIZE. Luckily PAGE_SIZE is unsigned long which made the compare an
+unsigned compare, meaning the negative size value did not end up causing a
+large portion of memory to be randomly zeroed out.
