      ALSA: sound/usb: Use negated usb_endpoint_xfer_control, etc · 913ae5a2
      Julia Lawall authored
      This patch extends 42a6e66f by using
      usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk,
      and usb_endpoint_xfer_int in the negated case as well.
      This patch also rewrites some calls to usb_endpoint_dir_in as negated calls
      to !usb_endpoint_dir_out, and vice versa, to better correspond to the
      intent of the original code.
      The semantic patch that makes this change is as follows:
      // <smpl>
      @@ struct usb_endpoint_descriptor *epd; @@
      - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_CONTROL\|0\))
      + !usb_endpoint_xfer_control(epd)
      @@ struct usb_endpoint_descriptor *epd; @@
      - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_ISOC\|1\))
      + !usb_endpoint_xfer_isoc(epd)
      @@ struct usb_endpoint_descriptor *epd; @@

      ALSA: sound/usb: use USB API functions rather than constants · 42a6e66f
      Julia Lawall authored
      This set of patches introduces calls to the following set of functions:

      just replaces an explicit integer value by one of the following constants:

      ALSA: snd_usb_audio: fix SB Extigy IR Remote regression · b9c196e1
      Phillip Michael Jordan authored
      The support for the SB Extigy's remote seems to be broken in all
      recent ALSA versions, including 1.0.17. The driver detects the event
      correctly, then submits a URB to query the RC code. On the Extigy, the
      URB is submitted with a length of 2 bytes. My hardware, however, only
      replies with 1 byte, containing the correct RC button code. The
      current implementation discards this as being too short. (line 1784 of
      This patch specifies a "minimum packet length" in the remote control
      configuration. I've left the values for the Audigy 2/Live! the same as
      the packet length, as I'm assuming the existing code works with them.
      (I don't have the hardware to confirm) This fixes the Extigy RC
      support, e.g. for use with Lirc.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      David Howells authored
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
      of passing regs around manually through all ~1800 interrupt handlers in the
      Linux kernel.
      The regs pointer is used in few places, but it potentially costs both stack
      space and code to pass it around.  On the FRV arch, removing the regs parameter
      from all the genirq function results in a 20% speed up of the IRQ exit path
      (ie: from leaving timer_interrupt() to leaving do_IRQ()).
      Where appropriate, an arch may override the generic storage facility and do
      something different with the variable.  On FRV, for instance, the address is
      maintained in GR28 at all times inside the kernel as part of general exception
      Having looked over the code, it appears that the parameter may be handed down
      through up to twenty or so layers of functions.  Consider a USB character
      device attached to a USB hub, attached to a USB controller that posts its
      interrupts through a cascaded auxiliary interrupt controller.  A character
      device driver may want to pass regs to the sysrq handler through the input
      layer which adds another few layers of parameter passing.
      I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
      main part of the code on FRV and i386, though I can't test most of the drivers.
      I've also done partial conversion for powerpc and MIPS - these at least compile
      with minimal configurations.
      This will affect all archs.  Mostly the changes should be relatively easy.
      Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
      	struct pt_regs *old_regs = set_irq_regs(regs);
      And put the old one back at the end:
      Don't pass regs through to generic_handle_irq() or __do_IRQ().
      In timer_interrupt(), this sort of change will be necessary:
      	-	update_process_times(user_mode(regs));
      	-	profile_tick(CPU_PROFILING, regs);
      	+	update_process_times(user_mode(get_irq_regs()));
      	+	profile_tick(CPU_PROFILING);
      I'd like to move update_process_times()'s use of get_irq_regs() into itself,
      except that i386, alone of the archs, uses something other than user_mode().
      Some notes on the interrupt handling in the drivers:
       (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
           the input_dev struct.
       (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
           something different depending on whether it's been supplied with a regs
           pointer or not.
       (*) Various IRQ handler function pointers have been moved to type

      [ALSA] Remove redundant NULL checks before kfree · 4d572776

      Checking a pointer for NULL before calling kfree() on it is redundant,
      kfree() deals with NULL pointers just fine.
      This patch removes such checks from sound/
      This patch also makes another, but closely related, change.
      It avoids casting pointers about to be kfree()'ed.
