staging: prefix header search paths with $(srctree)/

2019-02-04T11:30:27+00:00

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

This patch adds the missing release function for the DCI device that frees
the container structure it is embedded in.

staging: most: fix label names

2018-09-25T19:09:56+00:00

This patch makes use of label names that say what the goto
actually does, as recommended in the kernel documentation.

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).
