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>

Now we may declare const for snd_device_ops definitions, so let's do it for optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-10-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-12-11ALSA: lola: Support PCM sync_stopTakashi Iwai
The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation, as well as removing the superfluous synchronize_irq() call.

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>
