+Subject: [PATCH 1/2] ALSA: usb-audio: Fix packet size calculation
+
+Commit f0bd62b64016 ("ALSA: usb-audio: Improve frames size computation")
+introduced a regression for devices which have playback endpoints with
+bInterval > 1. Fix this by taking ep->datainterval into account.
+
+Note that frame and fps are actually mean packet and packets per second
+in the code introduces by the mentioned commit. This will be fixed in a
+follow-up patch.

+Subject: [PATCH 2/2] drm/amd/display: Only revalidate bandwidth on medium and
+ fast updates
+
+[Why]
+Changes that are fast don't require updating DLG parameters making
+this call unnecessary. Considering this is an expensive call it should
+not be done on every flip.
+
+[How]
+Guard the validation to only happen if update type isn't FAST.
