media: ene_ir: Fix driver initialisation

2012-08-15T15:10:05+00:00

commit b31b021988fed9e3741a46918f14ba9b063811db upstream.

commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR
registration") fixed an early ISR registration on several drivers.  It did
however also introduced a bug by moving the invocation of pnp_port_start()
to the end of the probe function.

This patch fixes this issue by moving the invocation of pnp_port_start() to
an earlier stage in the probe function.

media: dvb-core: Release semaphore on error path dvb_register_device()

2012-07-19T15:58:55+00:00

commit 82163edcdfa4eb3d74516cc8e9f38dd3d039b67d upstream.

There is a missing "up_write()" here. Semaphore should be released
before returning error value.

media: cx231xx: don't DMA to random addresses

2012-07-19T15:58:54+00:00

commit a7deca6fa79d5c65575532e780f3c93f6bf8ddad upstream.

Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

commit 31c5f0c5e25ed71eeced170f113bb590f2f1f6f3 upstream.

Properly validate the user-supplied index against the number of inputs.
The code used the pin local variable instead of the index by mistake.
