staging: most: video: fix build warnings

2018-05-14T09:42:28+00:00

Commit 7d7cdb4fa552 ("staging: most: video: remove debugging code") ended up
adding a bunch of build warnings about unused variables.  Fix that up by
removing those variables as we don't need them anymore.

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: dim2: use device to allocate coherent memory

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

On several architectures the allocation of coherent memory needs a device
that has the dma_ops structure properly initialized. This patch enables
the DIM2 platform to be used to allocate this type of memory.

that do platform specific initialization and supply the IRQ number.
Instead DT code is added
