2022-04-12ALSA: lola: 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(). This patch fixes it by calling snd_card_free() on the error from the probe callback using a new helper function. Fixes: 098fe3d6e775 ("ALSA: lola: Allocate resources with device-managed APIs") Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20220412102636.16000-30-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-07-19ALSA: lola: Allocate resources with device-managed APIsTakashi Iwai
This patch converts the resource management in PCI lola driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, the page allocations are done with the devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-41-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

2021-01-08ALSA: Convert strlcpy to strscpy when return value is unusedJoe Perches
strlcpy is deprecated. see: Documentation/process/deprecated.rst Change the calls that do not use the strlcpy return value to the preferred strscpy. Done with cocci script: @@ expression e1, e2, e3; @@ - strlcpy( + strscpy( e1, e2, e3); This cocci script leaves the instances where the return value is used unchanged. After this patch, sound/ has 3 uses of strlcpy() that need to be manually inspected for conversion and changed one day. $ git grep -w strlcpy sound/ sound/usb/card.c: len = strlcpy(card->longname, s, sizeof(card->longname)); sound/usb/mixer.c: return strlcpy(buf, p->name, buflen); sound/usb/mixer.c: return strlcpy(buf, p->names[index], buflen); Miscellenea: o Remove trailing whitespace in conversion of sound/core/hwdep.c Link: https://lore.kernel.org/lkml/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/ Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/22b393d1790bb268769d0bab7bacf0866dcb0c14.camel@perches.com Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-07-27ALSA: lola: Proper endian notationsTakashi Iwai
The BDL entries in lola driver are little-endian while we code them as u32. This leads to sparse warnings like: sound/pci/lola/lola.c:105:40: warning: incorrect type in assignment (different base types) sound/pci/lola/lola.c:105:40: expected unsigned int [unsigned] [usertype] <noident> sound/pci/lola/lola.c:105:40: got restricted __le32 [usertype] <noident> This patch fixes the declarations to the proper __le32 type. Also, there was a typo in the original code, where __user was used that was intended as __iomem. This was caused also by sparse: sound/pci/lola/lola_mixer.c:132:27: warning: incorrect type in assignment (different address spaces) Fixed in this patch as well.

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. In general, it's simpler and more readable when the module name appears there, so let's replace all entries with KBUILD_MODNAME. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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>

2011-05-03ALSA: Add the driver for Digigram Lola PCI-e boardsTakashi Iwai
Added a new driver for supporting Digigram Lola PCI-e boards. Lola has a similar h/w design like HD-audio but with extended verbs. Thus the driver is written similarly like HD-audio driver in the bus part. The codec part is rather written in a fixed way specific to the Lola board because of the verb incompatibility. The driver provides basic PCM, supporting multi-streams and mixing. Signed-off-by: Takashi Iwai <tiwai@suse.de>
