media: pci: netup_unidvb: Stop direct calls to queue num_buffers field

Use vb2_get_num_buffers() to avoid using queue num_buffers field directly.
This allows us to change how the number of buffers is computed in the
future.

media: netup_unidvb: fix irq init by register it at the end of probe

IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.

Spinlock dma->lock and i2c->lock suffer from the same problem.

Fix this by registering the irq at the end of probe.

media: netup_unidvb: fix use-after-free at del_timer()

When Universal DVB card is detaching, netup_unidvb_dma_fini()
uses del_timer() to stop dma->timeout timer. But when timer
handler netup_unidvb_dma_timeout() is running, del_timer()
could not stop it. As a result, the use-after-free bug could
happen. The process is shown below:

(cleanup routine) | (timer routine)
| mod_timer(&dev->tx_sim_timer, ..)
netup_unidvb_finidev() | (wait a time)
netup_unidvb_dma_fini() | netup_unidvb_dma_timeout()
del_timer(&dma->timeout); |
| ndev->pci_dev->dev //USE

Fix by changing del_timer() to del_timer_sync().

media: netup_unidvb: handle interrupt properly according to the firmware

The interrupt handling should be related to the firmware version. If
the driver matches an old firmware, then the driver should not handle
interrupt such as i2c or dma, otherwise it will cause some errors.

media: netup_unidvb: drop initialization of PM pointers

The .suspend() and .resume() callbacks are not defined for this driver.
Thus, just the unlisting of PM pointers in the struct initializer will make
no change in its behavior. Still unlisting is necessary so as to get rid of
.suspend and .resume pointers as they are part of the legacy framework and
should not be used in the driver code explicitly.

[media] dvb-frontends/cxd2841er: make call to i2c_gate_ctrl optional

Some cards/bridges wrap i2c_gate_ctrl handling with a mutex_lock(). This is
e.g. done in ddbridge to protect against concurrent tuner access with
regards to the dual tuner HW, where concurrent tuner reconfiguration can
result in tuning fails or bad reception quality. When the tuner driver
additionally tries to open the I2C gate (which e.g. the tda18212 driver
does) when the demod already did this, this will lead to a deadlock. This
makes the calls to i2c_gatectrl from the demod driver optional when the
flag is set, leaving this to the tuner driver. For readability reasons and
to not have the check duplicated multiple times, the setup is factored
into cxd2841er_tuner_set().

This commit also updates the netup card driver (which seems to be the only
consumer of the cxd2841er as of now).

Make this a proper typed array. Drop the old allocate context code since
that is no longer used.

Note that the memops functions now get a struct device pointer instead of

a struct containing only a struct device pointer).

This code is now a lot cleaner.

[media] vb2: drop v4l2_format argument from queue_setup

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.

After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.

To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

[media] media: videobuf2: Restructure vb2_buffer

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.

Add new member variables - bytesused, length, offset, userptr, fd,
data_offset - to struct vb2_plane in order to cover all information
of v4l2_plane.
struct vb2_plane {
<snip>
unsigned int bytesused;
unsigned int length;
union {
unsigned int offset;
unsigned long userptr;
int fd;
} m;
unsigned int data_offset;
}

Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
<snip>
unsigned int index;
unsigned int type;
unsigned int memory;
unsigned int num_planes;
struct vb2_plane planes[VIDEO_MAX_PLANES];
<snip>
};

v4l2 specific fields - flags, field, timestamp, timecode,
sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
struct vb2_v4l2_buffer {
struct vb2_buffer vb2_buf;

__u32 flags;
__u32 field;
struct timeval timestamp;
struct v4l2_timecode timecode;
__u32 sequence;
};
