staging: most: usb: remove local variable

2018-05-08T11:41:51+00:00

This patch removes the local variable dev that is used to store the pointer
to the usb_device whenever it is used only once.

staging: most: usb: fix usb_disconnect race condition

2018-05-08T11:41:51+00:00

The functions usb_disconnect and usb_sndbulkpipe are racing for the struct
usb_device, which might cause a null pointer dereference exception. This
patch fixes this race condition by protecting the critical section inside
the function hdm_enque with the io_mutex.

staging: most: usb: don't set URB_ZERO_PACKET flag for synchronous data

2018-05-08T11:41:51+00:00

This patch avoids setting the URB_ZERO_PACKET transfer flag for synchronous
data. This is needed to prevent the host from sending an empty packet when
data is aligned to an endpoint packet boundary.

staging: most: usb: add ep number to log

2018-05-08T11:41:50+00:00

This patch adds the endpoint number of the USB pipe that reports to be
broken into the log message. It is needed to make debugging for
applications more comfortable.

staging: most: sound: call snd_card_new with struct device

2018-05-08T11:41:50+00:00

This patch is needed as function snd_card_new needs a valid
parent device. Passing a NULL pointer leads to kernel Ooops.

staging: most: make interface drivers allocate coherent memory

2018-05-08T11:41:50+00:00

On arm64/aarch64 architectures the allocation of coherent memory needs a
device that has the dma_ops properly set. That's why the core module of
the MOST driver is no longer able to allocate this type or memory. This
patch moves the allocation process down to the interface drivers where
the proper devices exist (e.g. platform device or USB system software).

staging: most: Fix identifiers to function parameters

2018-01-08T15:34:25+00:00

fixed "function definition argument should have an identifier name",
with appropriate identifier names. Pointed out by checkpatch.

staging: most: make DEVICE_ATTR structures static

In order to limit the scope of the DEVICE_ATTR structure this patch
adds the keywork static.

staging: most: usb: fix show/store function names

2017-11-27T08:20:37+00:00

This patch renames the show/store functions of the USB module.
It is needed to make the module meet the established naming
convention.

staging: most: usb: clear functional stall on OUT endpoint

2017-11-27T08:20:36+00:00

For the MOST packet channel there are two dedicated USB endpoints. But
internally the hardware has actually one channel for data forwarding from
and to MOST. To have the hardware clean up its state machine correctly in
case of an error, both USB pipes need to be reset.  This patch triggers the
host to also clear the OUT endpoint's halt condition in case an IN endpoint
has signaled to be stalled.
