      ASoC: wm8904: Correct number of EQ registers · 97aff2c0
      Charles Keepax authored
      
      
      There are 24 EQ registers not 25, I suspect this bug came about because
      the registers start at EQ1 not zero. The bug is relatively harmless as
      the extra register written is an unused one.

      ALSA: hda - Fix deadlock at error in building PCM · d289619a
      Takashi Iwai authored
      The HDA codec driver issues snd_hda_codec_reset() at the error path of
      PCM build.  This was needed in the earlier code base, but the recent
      rewrite to use the standard bus binding made this a deadlock:

       "Here are two patches, the first of which at least should go upstream
        immediately:
      
        (1) Prevent a user-triggerable crash in the keyrings destructor when a
            negatively instantiated keyring is garbage collected.  I have also
            seen this triggered for user type keys.
      
        (2) Prevent the user from using requesting that a keyring be created
            and instantiated through an upcall.  Doing so is probably safe
            since the keyring type ignores the arguments to its instantiation
            function - but we probably shouldn't let keyrings be created in
            this manner"

      um: Fix waitpid() usage in helper code · 6b187337
      Richard Weinberger authored
      
      
      If UML is executing a helper program it is using
      waitpid() with the __WCLONE flag to wait for the program
      as the helper is executed from a clone()'ed thread.
      While using __WCLONE is perfectly fine for clone()'ed
      childs it won't detect terminated childs if the helper
      has issued an execve().
      
      We have to use __WALL to wait for both clone()'ed and
      regular childs to detect the termination before and
      after an execve().

      um: Do not rely on libc to provide modify_ldt() · 37e81a01
      Hans-Werner Hilse authored
      
      
      modify_ldt() was declared as an external symbol. Despite the man
      page for this syscall telling that there is no wrapper in glibc,
      since version 2.1 there actually is, so linking to the glibc
      works.
      
      Since modify_ldt() is not a POSIX interface, other libc
      implementations do not always provide a wrapper function.
      Even glibc headers do not provide a corresponding declaration.
      
      So go the recommended way to call this using syscall().

      PWM fan control is only available with DPM.  There is no non-DPM

      KEYS: Don't permit request_key() to construct a new keyring · 911b79cd
      David Howells authored
      
      
      If request_key() is used to find a keyring, only do the search part - don't
      do the construction part if the keyring was not found by the search.  We
      don't really want keyrings in the negative instantiated state since the
      rejected/negative instantiation error value in the payload is unioned with
      keyring metadata.
      
      Now the kernel gives an error:
      
      	request_key("keyring", "#selinux,bdekeyring", "keyring", KEY_SPEC_USER_SESSION_KEYRING) = -1 EPERM (Operation not permitted)
