https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.3 This is a very big update, mainly thanks to Morimoto-san's refactoring work and some fairly large new drivers. - Lots more work on moving towards a component based framework from Morimoto-san. - Support for force disconnecting muxes from Jerome Brunet. - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308.

2019-07-05ALSA: cs4281: remove redundant assignment to variable val and remove a gotoColin Ian King
The variable val is being assigned with a value that is never read and it is being updated later with a new value. The assignment is redundant and can be removed. Also remove a goto statement and a label and replace with a break statement.

2015-01-09ALSA: cs4281: Simplify PM callbacksTakashi Iwai
This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801: PCI core handles power state for us]. Since pci_set_power_state(), pci_save_state() and pci_restore_state() are already done in the PCI core side, so we don't need to it doubly. Also, pci_enable_device(), pci_disable_device() and pci_set_master() calls in PM callbacks are superfluous nowadays, too, so get rid of them as well. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-05-29ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at removeTakashi Iwai
As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-06-10ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*Takashi Iwai
The name argument of request_irq() appears in /proc/interrupts, and it's quite ugly when the name entry contains a space or special letters.

2011-06-10ALSA: Use KBUILD_MODNAME for pci_driver.name entriesTakashi Iwai
The convention for pci_driver.name entry in kernel drivers seem to be the module name or equivalent ones. But, so far, almost all PCI sound drivers use more verbose name like "ABC Xyz (12)", and these are fairly confusing when appearing as a file name. This patch converts the all pci_driver.name entries in sound/pci/* to use KBUILD_MODNAME for more unified appearance. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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 handling. 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: set_irq_regs(old_regs); 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 irq_handler_t.
