[media] av7110: convert set_fontend to use DVBv5 parameters

2011-12-31T11:15:04+00:00

Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.

Also, fill the supported delivery systems at dvb_frontend_ops
struct.

[media] Rename set_frontend fops to set_frontend_legacy

2011-12-31T11:09:43+00:00

Passing DVBv3 parameters to set_frontend is not fun, as the
core doesn't have any way to know if the driver is using the
v3 or v5 parameters. So, rename the callback and add a new
one to allow distinguish between a mixed v3/v5 paramenter call
from a pure v5 call.

After having all frontends to use the new way, the legacy
call can be removed.

[media] tuners: remove dvb_frontend_parameters from set_params()

2011-12-31T10:57:29+00:00

This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.

After this change, very few DVBv3 specific stuff are left at the
tuners.

[media] budget-ci: Fix Hauppauge RC-5 IR support

2011-12-18T00:15:02+00:00

Hauppauge RC-5 tables require the full scancodes. The code at budget-ci
handles it right, however, it request the rc-code to mask them with 0xff,
breaking support for some remote controllers.

Fix it by not selecting a scancode mask when the driver is on full_rc5 mode.

[media] av7110: wrong limiter in av7110_start_feed()

2011-11-24T16:26:02+00:00

Smatch complains that the wrong limiter is used here:
drivers/media/dvb/ttpci/av7110.c +906 dvb_feed_start_pid(12)
	error: buffer overflow 'npids' 5 <= 19

Here is the problem code:
   905          i = dvbdmxfeed->pes_type;
   906          npids[i] = (pid[i]&0x8000) ? 0 : pid[i];

"npids" is a 5 element array declared on the stack.  If
dvbdmxfeed->pes_type is more than 4 we probably put a (u16)0 past
the end of the array.

If dvbdmxfeed->pes_type is over 4 the rest of the function doesn't
do anything.  dvbdmxfeed->pes_type is capped at less than
DMX_TS_PES_OTHER (20) in the caller function, but I changed it to
less than or equal to DMX_TS_PES_PCR (4).
