2022-04-12ALSA: cs5535audio: Fix the missing snd_card_free() call at probe errorTakashi Iwai
The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free().

2021-07-19ALSA: cs5535audio: Allocate resources with device-managed APIsTakashi Iwai
This patch converts the resource management in PCI cs5535audio driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. A slight uncertain change is the call of olpc_quirks_cleanup() at removal: formerly this was called unconditionally at remove, but this should be a conditionally call, hence the machine_is_olpc() check is added here as well. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-32-tiwai@suse.de 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>

2009-12-15ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimizationAndres Salomon
Previously, OLPC support for the mic extensions was only enabled in the ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was because the old geode GPIO code was written in a manner that assumed CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead include a requirement on GPIOLIB. We use the generic GPIO API rather than the cs553x-specific API.

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.
