2015-01-28ALSA: Include linux/uaccess.h and linux/bitopts.h instead of asm/*Takashi Iwai
Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-04ALSA: Deletion of checks before the function call "iounmap"Markus Elfring
The iounmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-12-31ALSA: asihpi: fix an information leak in asihpi_hpi_ioctl()Eliot Blennerhassett
Add missing limits to keep copied data within allocated buffer. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-12-02ALSA: asihpi: Deletion of an unnecessary check before the function call "vfree"Markus Elfring
The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-22ALSA: asihpi: don't fail probe if adapter mode read failsEliot Blennerhassett
Only determining if low latency mode is enabled. Failure indicates adapter has no modes Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-22ALSA: asihpi: Add support for stream interrupt.Eliot Blennerhassett
Some cards have a so-called low-latency mode, in which they present a single multichannel stream with no mixing or samplerate conversion. In this mode the card can generate an interrupt per internal processing block (typically 32 or 64 frames) Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> 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>
2012-12-07ALSA: pci: remove __dev* attributesBill Pemberton
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-10-28ALSA: Convert dev_printk(KERN_<LEVEL> to dev_<level>(Joe Perches
dev_<level> calls take less code than dev_printk(KERN_<LEVEL> and reducing object size is good. Coalesce multiline formats for easier grep. Coalesce segmented single line formats too. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-12-22ALSA: asihpi - Remove redundant struct members.Eliot Blennerhassett
Structs hpi_adapter and snd_card_asihpi had members that duplicate those in underlying hpi_adapter_obj or whose info can be retrieved using hpi_adapter_get_info(). Print less info in probe function, it can be retrieved from /proc. Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-12-22ALSA: asihpi - Split hpi version info into separate header file.Eliot Blennerhassett
and update HPI version to 4.10 Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-10-31sound: Add module.h to the previously silent sound usersPaul Gortmaker
Lots of sound drivers were getting module.h via the implicit presence of it in <linux/device.h> but we are going to clean that up. So fix up those users now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-08-02ALSA: asihpi - Clarify adapter index validity checkEliot Blennerhassett
Avoids assigning possibly invalid address to pa, even if it is never dereferenced. Correct error response to reflect request object/function ids. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-07-27ALSA: asihpi - off by one in asihpi_hpi_ioctl()Dan Carpenter
"adapter" is used as an array index in the adapters[] array so the off by one would make us read past the end. 1c073b67979 "ALSA: asihpi - Remove spurious adapter index check" reverted Dan Rosenberg's check that would have prevented the overflow here. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-07-27ALSA: asihpi - bug fix pa use before init.Eliot Blennerhassett
Fixes bug introduced by 1c073b67. Also declare pa local to block in which it is used. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-07-22ALSA: asihpi - Remove spurious adapter index checkEliot Blennerhassett
Subsystem requests don't have or need a valid adapter index. The adapter index is already checked further on, before it is used to index the adapters array. (Reverts 4a122c10f) Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-04-05ALSA: asihpi: Simplify driver unload cleanupEliot Blennerhassett
Replacing subsys_delete_adapter with adapter_delete allows some special-case adapter lookup code to be removed. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-03-18ALSA: sound/pci/asihpi: check adapter index in hpi_ioctlDan Rosenberg
The user-supplied index into the adapters array needs to be checked, or an out-of-bounds kernel pointer could be accessed and used, leading to potentially exploitable memory corruption.

2011-02-10ALSA: asihpi - Interrelated HPI tidy up.Eliot Blennerhassett
Remove many unused functions. Update some message and cache structs. Use pci info directly from pci_dev. Allow control cache elements with variable size, and handle large message/response from dsp. hpi6000 and hpi6205: fix error path when adapter bootload fails. hpimsgx.c get rid of code duplicated in hpicmn.c Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
