This driver implements a fake get_bandwidth() callback. In reallity, the tuner driver won't adjust its low-pass filter based on a bandwidth, and were just providing a fake method for demods to read whatever was "set". This code is useless, as none of the drivers that use this tuner seems to require a get_bandwidth() callback. While here, convert set_params to use the DVBv5 way to pass parameters to tuners.

Instead of just estimating the bandwidth for DVB-C annex A/C, also fill it at the core for ATSC and DVB-C annex B. This simplifies the logic inside the tuners, as all non-satellite tuners can just use c->bandwidth_hz for all supported delivery systems. It could make sense to latter use it also for satellite systems, as several DVB-S drivers have their own calculus. However, on DVB-S2 the bw estimation is a little more complex, and the existing drivers have some optimized calculus for bandwidth. So, let's not touch on it for now. Signed-off-by: -

SYS_DVBC_ANNEX_AC is an alias for SYS_DVBC_ANNEX_A. However, the first one is incorrect, as not all devices support both. So, replace its occurrences by the proper value (either SYS_DVBC_ANNEX_A or both SYS_DVBC_ANNEX_A and SYS_DVBC_ANNEX_C). Signed-off-by:

dvb_register calls videobuf_dvb_register_bus, but if that returns a failure the module will be unloaded without clearing the value of core->gate_ctrl which will cause an oops in macros called from video_open in cx88-video.c Signed-off-by:

Hi Mauro, I have made a small mistake on this patch. I forgot to increase number of num_device_descs to 4. Signed-off-by:

The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107Signed-off-by:

There are some issues and miss-behaves at the dvb fe thread: 1) dvb_shutdown_timeout should be dvb_shutdown_timeout * HZ instead of (dvb_shutdown_timeout * HZ + 1); 2) add a memory barrier to warrant that all CPU's will consider the new value for release_jiffies; 3) wake up dvb thread also when fepriv->exit == DVB_FE_NO_EXIT.

It seems that a cut-and-past error were added by the last patch: drivers/media/video/videobuf2-core.c: In function ‘vb2_qbuf’: drivers/media/video/videobuf2-core.c:1099:14: warning: comparison between ‘enum v4l2_buf_type’ and ‘enum v4l2_memory’ [-Wenum-compare] On all places V4L2_MEMORY_USERPTR is used, it is associated with q->memory, and not b->type. So, the fix seems obvious.

To get direct access to userspace memory pages vb2 allocator needs to gather read access on mmap semaphore in the current process. The same semaphore is taken before calling mmap operation, while both mmap and qbuf are called by the driver or v4l2 core with driver's lock held. To avoid a AB-BA deadlock (mmap_sem then driver's lock in mmap and driver's lock then mmap_sem in qbuf) the videobuf2 core release driver's lock, takes mmap_sem and then takes again driver's lock. get_userptr methods are now called with all needed locks already taken to avoid further lock magic inside memory allocator's code.

Heuristic that checks if the memory pointer has been changed lacked a check if the pointer was actually provided by the userspace, what allowed one to queue a NULL pointer which was accepted without further checking. This patch fixes this issue. Reported-by:

AF9015 firmware does not like if it gets interrupted by I2C adapter request on some critical phases. During normal operation I2C adapter is used only 2nd demodulator and tuner on dual tuner devices. Override demodulator callbacks and use mutex for limit access to those "critical" paths to keep AF9015 happy. Signed-off-by:

This is prerequisite for enabling the sub-device node. The control handler is now initialized in driver's probe callback in order to allow the user space access controls before the device power is enabled with s_power. This is needed due to s_power being currently called only by the host driver. It also adds the subdev internal operations, only open() for now for the TRY format initialization. Acked-by:
