2024-05-08ALSA: usb: Use *-y instead of *-objs in MakefileTakashi Iwai1-1/+1
*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

2021-10-27ALSA: ua101: fix division by zero at probeJohan Hovold1-2/+2
Add the missing endpoint max-packet sanity check to probe() to avoid division by zero in alloc_stream_buffers() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

2021-03-17module: remove never implemented MODULE_SUPPORTED_DEVICELeon Romanovsky1-1/+0
MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not.

2020-09-09ALSA: ua101: Replace tasklet with workTakashi Iwai1-8/+8
The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In UA101 driver, a tasklet is still used for handling the output URBs. It can be achieved gracefully with a work queued in the high-prio system workqueue, too. This patch replaces the tasklet usage in UA101 driver with a simple work.

2013-04-29ALSA: USB: adjust for changed 3.8 USB APIClemens Ladisch1-2/+1
The recent changes in the USB API ("implement new semantics for URB_ISO_ASAP") made the former meaning of the URB_ISO_ASAP flag the default, and changed this flag to mean that URBs can be delayed. This is not the behaviour wanted by any of the audio drivers because it leads to discontinuous playback with very small period sizes. Therefore, our URBs need to be submitted without this flag.

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option.

2011-11-06ALSA: ua101: fix crash when unpluggingClemens Ladisch1-7/+21
If the device is unplugged while running, it is possible for a PCM device to be closed after the disconnect callback has returned. This means that kill_stream_urb() and disable_iso_interface() would try to access already-invalid or freed USB data structures. The function free_usb_related_resources() was intended to prevent this, but forgot to clear the affected variables.

2010-03-05ALSA: usb-audio: refactor codeDaniel Mack1-1/+1
Clean up the usb audio driver by factoring out a lot of functions to separate files. Code for procfs, quirks, urbs, format parsers etc all got a new home now. Moved almost all special quirk handling to quirks.c and introduced new generic functions to handle them, so the exceptions do not pollute the whole driver. Renamed usbaudio.c to card.c because this is what it actually does now. Renamed usbmidi.c to midi.c for namespace clarity. Removed more things from usbaudio.h.
