Subject: [PATCH AUTOSEL 5.12 087/104] ALSA: usb-audio: scarlett2: Fix scarlett2_*_ctl_put() return values

From: "Geoffrey D. Bennett" <g@...vu>

[ Upstream commit c5d8e008032f3cd5f266d552732973a960b0bd4b ]

Mixer control put callbacks should return 1 if the value is changed.
Fix the sw_hw, level, pad, and button controls accordingly.
