      ALSA: pci: Simplify with dma_set_mask_and_coherent() · 669f65ea
      Takashi Iwai authored 
      Many PCI drivers still have two explicit calls of dma_set_mask() and
dma_set_coherent_mask().

Let's simplify with dma_set_mask_and_coherent().

      ALSA: dice: add support for Lexicon I-ONIX FW810s · 9a08676f
      Takashi Sakamoto authored 
      I-ONIX FW810s was shipped in Lexicon brand of HARMAN International
industries, Inc 2009. The model uses TCD2220 ASIC as its communication
engine. TCAT general protocol is supported, its extension isn't.

This patch adds support for the model with hard-coded stream formats.

      ALSA: usb-audio: Convert the last strlcpy() usage · 42ef170d
      Takashi Iwai authored 
      The last remaining usage of strlcpy() in USB-audio driver is the setup
of the card longname string.  Basically we need to know whether any
non-empty string is set or not, and no real length is needed.
Refactor the code and use strscpy() instead.  After this change,
strlcpy() is gone from all sound/* code.

      ALSA: usb-audio: Convert remaining strlcpy() to strscpy() · e8afdfdc
      Takashi Iwai authored 
      USB-audio driver still contains two calls of strlcpy() because the
return size is evaluated.  Basically it just checks whether the string
is copied or not, but since strcpy() may return a negative error code,
we should check the negative value and treat as filled.

      ALSA: hda/via: Fix runtime PM for Clevo W35xSS · 4bfd6247
      Takashi Iwai authored 
      Clevo W35xSS_370SS with VIA codec has had the runtime PM problem that
looses the power state of some nodes after the runtime resume.  This
was worked around by disabling the default runtime PM via a denylist
entry.  Since 5.10.x made the runtime PM applied (casually) even
though it's disabled in the denylist, this problem was revisited.  The
result was that disabling power_save_node feature suffices for the
runtime PM problem.

This patch implements the disablement of power_save_node feature in
VIA codec for the device.  It also drops the former denylist entry,
too, as the runtime PM should work in the codec side properly now.

Fixes: b529ef24 ("ALSA: hda: Add Clevo W35xSS_370SS to the power_save blacklist")

      drm/amd/display: avoid uninitialized variable warning · 61d79136
      Linus Torvalds authored 
      clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.

So just initialize 'val' to zero to avoid the issue.

      genirq: Fix export of irq_to_desc() for powerpc KVM · 11cc92eb
      Michael Ellerman authored 
      Commit 64a1b95b ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() unless powerpc KVM is being built, because
there is still a use of irq_to_desc() in modular code there.

However it used:

  #ifdef CONFIG_KVM_BOOK3S_64_HV

Which doesn't work when that symbol is =m, leading to a build failure:

  ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!

Fix it by checking for the definedness of the correct symbol which is
CONFIG_KVM_BOOK3S_64_HV_MODULE.

Fixes: 64a1b95b ("genirq: Restrict export of irq_to_desc()")
