+Subject: ALSA: echoaudio: Remove incorrect part of assertion
+
+From: Mark Hills <mark@pogo.org.uk>
+
+commit c914f55f7cdfafe9d7d5b248751902c7ab57691e upstream.
+
+This assertion seems to imply that chip->dsp_code_to_load is a pointer.
+It's actually an integer handle on the actual firmware, and 0 has no
+special meaning.
+
+The assertion prevents initialisation of a Darla20 card, but would also
+affect other models. It seems it was introduced in commit dd7b254d.

+Subject: ALSA: HDA: Lessen CPU usage when waiting for chip to respond
+
+From: David Henningsson <david.henningsson@canonical.com>
+
+commit 32cf4023e689ad5b3a81a749d8cc99d7f184cb99 upstream.
+
+When an IRQ for some reason gets lost, we wait up to a second using
+udelay, which is CPU intensive. This patch improves the situation by
+waiting about 30 ms in the CPU intensive mode, then stepping down to
+using msleep(2) instead. In essence, we trade some granularity in
+exchange for less CPU consumption when the waiting time is a bit longer.
+
+As a result, PulseAudio should no longer be killed by the kernel
+for taking up to much RT-prio CPU time. At least not for *this* reason.
