+Subject: ALSA: hdmi: Expose all pins on MSI MS-7C94 board
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 33f735f137c6539e3ceceb515cd1e2a644005b49 upstream.
+
+The BIOS on MSI Mortar B550m WiFi (MS-7C94) board with AMDGPU seems
+disabling the other pins than HDMI although it has more outputs
+including DP.
+
+This patch adds the board to the allow list for enabling all pins.

+Subject: ALSA: sb: Fix potential ABBA deadlock in CSP driver
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 1c2b9519159b470ef24b2638f4794e86e2952ab7 upstream.
+
+SB16 CSP driver may hit potentially a typical ABBA deadlock in two
+code paths:
+
+ In snd_sb_csp_stop():
+ spin_lock_irqsave(&p->chip->mixer_lock, flags);
+ spin_lock(&p->chip->reg_lock);
+
+ In snd_sb_csp_load():
+ spin_lock_irqsave(&p->chip->reg_lock, flags);
+ spin_lock(&p->chip->mixer_lock);
+
+Also the similar pattern is seen in snd_sb_csp_start().
+
+Although the practical impact is very small (those states aren't
+triggered in the same running state and this happens only on a real
+hardware, decades old ISA sound boards -- which must be very difficult
+to find nowadays), it's a real scenario and has to be fixed.
+
+This patch addresses those deadlocks by splitting the locks in
+snd_sb_csp_start() and snd_sb_csp_stop() for avoiding the nested
+locks.

+Subject: ALSA: usb-audio: Add missing proc text entry for BESPOKEN type
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 64752a95b702817602d72f109ceaf5ec0780e283 upstream.
+
+Recently we've added a new usb_mixer element type, USB_MIXER_BESPOKEN,
+but it wasn't added in the table in snd_usb_mixer_dump_cval(). This
+is no big problem since each bespoken type should have its own dump
+method, but it still isn't disallowed to use the standard one, so we
+should cover it as well. Along with it, define the table with the
+explicit array initializer for avoiding other pitfalls.

+Subject: s390/boot: fix use of expolines in the DMA code
+
+From: Alexander Egorenkov <egorenar@linux.ibm.com>
+
+commit 463f36c76fa4ec015c640ff63ccf52e7527abee0 upstream.
+
+The DMA code section of the decompressor must be compiled with expolines
+if Spectre V2 mitigation has been enabled for the decompressed kernel.
+This is required because although the decompressor's image contains
+the DMA code section, it is handed over to the decompressed kernel for use.
+
+Because the DMA code is already slow w/o expolines, use expolines always
+regardless whether the decompressed kernel is using them or not. This
+simplifies the DMA code by dropping the conditional compilation of
+expolines.

+Subject: s390/ftrace: fix ftrace_update_ftrace_func implementation
+
+From: Vasily Gorbik <gor@linux.ibm.com>
+
+commit f8c2602733c953ed7a16e060640b8e96f9d94b9b upstream.
+
+s390 enforces DYNAMIC_FTRACE if FUNCTION_TRACER is selected.
+At the same time implementation of ftrace_caller is not compliant with
+HAVE_DYNAMIC_FTRACE since it doesn't provide implementation of
+ftrace_update_ftrace_func() and calls ftrace_trace_function() directly.
+
+The subtle difference is that during ftrace code patching ftrace
+replaces function tracer via ftrace_update_ftrace_func() and activates
+it back afterwards. Unexpected direct calls to ftrace_trace_function()
+during ftrace code patching leads to nullptr-dereferences when tracing
+is activated for one of functions which are used during code patching.
+Those function currently are:
+copy_from_kernel_nofault()
+copy_from_kernel_nofault_allowed()
+preempt_count_sub() [with debug_defconfig]
+preempt_count_add() [with debug_defconfig]

+Subject: xhci: Fix lost USB 2 remote wake
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit 72f68bf5c756f5ce1139b31daae2684501383ad5 upstream.
+
+There's a small window where a USB 2 remote wake may be left unhandled
+due to a race between hub thread and xhci port event interrupt handler.
+
+When the resume event is detected in the xhci interrupt handler it kicks
+the hub timer, which should move the port from resume to U0 once resume
+has been signalled for long enough.
+
+To keep the hub "thread" running we set a bus_state->resuming_ports flag.
+This flag makes sure hub timer function kicks itself.
+
+checking this flag was not properly protected by the spinlock. Flag was
+copied to a local variable before lock was taken. The local variable was
+then checked later with spinlock held.
+
+If interrupt is handled right after copying the flag to the local variable
+we end up stopping the hub thread before it can handle the USB 2 resume.
