2020-01-05ALSA: au88x0: More constificationsTakashi Iwai1-2/+2
Apply const prefix to each possible place: the static register tables, the coef tables, the string arrays, etc. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-14-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2020-01-03ALSA: pci: Constify snd_kcontrol_new itemsTakashi Iwai1-1/+1
Most of snd_kcontrol_new definitions are read-only and passed as-is. Let's declare them as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-38-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-12-11ALSA: pci: Drop superfluous ioctl PCM opsTakashi Iwai1-1/+0
PCM core deals the empty ioctl field now as default(*). Let's kill the redundant lines. (*) commit fc033cbf6fb7 ("ALSA: pcm: Allow NULL ioctl ops") Link: https://lore.kernel.org/r/20191210061145.24641-16-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-12-11ALSA: au88x0: Use managed buffer allocationTakashi Iwai1-12/+3
Clean up the drivers with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped. Link: https://lore.kernel.org/r/20191209094943.14984-26-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-12ALSA: au88x0: Fix incorrect device pointer for preallocationTakashi Iwai1-1/+1
The code change in commit 6974f8ad4494 ("ALSA: pci: Avoid non-standard macro usage") contained an incorrect conversion, which left the invalid pointer passed to the allocator for au88x0 driver. Fix it. Fixes: 6974f8ad4494 ("ALSA: pci: Avoid non-standard macro usage") Link: https://lore.kernel.org/r/20191112143243.22216-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-06ALSA: pci: Avoid non-standard macro usageTakashi Iwai1-1/+1
Pass the device pointer from the PCI pointer directly, instead of a non-standard macro. The macro didn't give any better readability. Link: https://lore.kernel.org/r/20191105151856.10785-24-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-06ALSA: pci: Drop superfluous snd_pcm_sgbuf_ops_pageTakashi Iwai1-1/+0
snd_pcm_sgbuf_ops_page is no longer needed to be set explicitly to PCM page ops since the recent change in the PCM core (*). Leaving it NULL should work as long as the preallocation has been done properly. This patch drops the redundant lines.

2016-04-26ALSA: au88x0: Fix overlapped PCM pointerTakashi Iwai1-1/+4
au88x0 hardware seems returning the current pointer at the buffer boundary instead of going back to zero. This results in spewing warnings from PCM core. This patch corrects the return value from the pointer callback within the proper value range, just returning zero if the position is equal or above the buffer size.

2014-10-15ALSA: au88x0: pr_* replaced with dev_*Sudip Mukherjee1-3/+3
pr_* macros replaced with dev_* as they are more preffered over pr_*. each file which had pr_* was reviewed manually and replaced with dev_*. here we have actually used the reference of the vortex which was added to some functions in the previous patch of this series. The prefix of the CARD_NAME and prefix of "vortex:" was also removed as the dev_* will print the device name.

added a pointer of the vortex in the following functions : vortex_alsafmt_aspfmt vortex_Vort3D_InitializeSource a3dsrc_ZeroStateA3D so that we can have a reference of the vortex in the function. this reference of the vortex will actually be used in a later patch to convert the pr_* macro to dev_*.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+548
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
