2021-06-21ALSA: usb-audio: scarlett2: Rename struct scarlett2_mixer_dataGeoffrey D. Bennett
Rename struct scarlett2_mixer_data to struct scarlett2_data. A less-wordy name is better because it is used everywhere, and although this is a mixer driver, it also controls other vendor-specific features. Signed-off-by: Geoffrey D. Bennett <g@b4.vu> Link: https://lore.kernel.org/r/20210620164639.GA9206@m.b4.vu Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-06-21ALSA: usb-audio: scarlett2: Rename buttons/interrupts/volGeoffrey D. Bennett
To match the vendor's terminology, change #defines, identifiers, and comments: - mute/dim/hardware buttons are now called dim/mute - mixer status/interrupt is now notify - vol is now monitor Signed-off-by: Geoffrey D.

2021-06-21ALSA: usb-audio: scarlett2: Remove redundant info->button_countGeoffrey D. Bennett
The per-model button_count value was used to determine whether dim/mute controls should be added, but these are present iff line_out_hw_vol is true. Remove button_count and replace with SCARLETT2_BUTTON_MAX and a check for line_out_hw_vol true. Signed-off-by: Geoffrey D.

2021-06-21ALSA: usb-audio: scarlett2: Remove interrupt debug messageGeoffrey D. Bennett
Just ignore instead of printing an error if the interrupt data is not the expected length. This check was for development and the condition has not been observed. Signed-off-by: Geoffrey D.

2021-06-21ALSA: usb-audio: scarlett2: Remove incorrect S/PDIF commentGeoffrey D. Bennett
The 18i8 Gen 2 S/PDIF outputs are available at 192kHz, unlike the 18i20 Gen 2. Remove the comment that says otherwise. Signed-off-by: Geoffrey D. Bennett <g@b4.vu> Link: https://lore.kernel.org/r/20210620164622.GA9155@m.b4.vu Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-06-08ALSA: usb-audio: scarlett2: Read mux at init timeGeoffrey D. Bennett

2021-05-21ALSA: usb-audio: scarlett2: Improve driver startup messagesGeoffrey D. Bennett
Add separate init function to call the existing controls_create function so a custom error can be displayed if initialisation fails. Use info level instead of error for notifications. Display the VID/PID so device_setup is targeted to the right device. Display "enabled" message to easily confirm that the driver is loaded. Signed-off-by: Geoffrey D.

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.

2020-09-16USB: move snd_usb_pipe_sanity_check into the USB coreGreg Kroah-Hartman
snd_usb_pipe_sanity_check() is a great function, so let's move it into the USB core so that other parts of the kernel, including the USB core, can call it. Name it usb_pipe_type_check() to match the existing usb_urb_ep_type_check() call, which now uses this function. Cc: Jaroslav Kysela <perex@perex.cz> Cc: "Gustavo A. R.

2020-02-01ALSA: usb-audio: Annotate endianess in Scarlett gen2 quirkTakashi Iwai
The Scarlett gen2 mixer quirk code defines a few record types to communicate via USB hub, and those must be all little-endian. This patch changes the field types to LE to annotate endianess properly. It also fixes the incorrect usage of leXX_to_cpu() in a couple of places, which was caught by sparse after this change.
