From: Matthias Schwarzott <zzam@gentoo.org>
This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.
The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.
Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.
So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)
The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

Since at least kernel 2.6.12-rc2, module.h includes moduleparm.h. This
patch removes all occurences of moduleparm.h from drivers/media files.

dvb_frontend
From: Patrick Boettcher <pb@linuxtv.org>
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.

dvb/frontends/at76c651.c: redefinition of __ilog2 blah blah
(akpm: I nuked __ilog2 and used the standard long_log2() instead)
We've already removed this module from the kernel, but
it is still in the v4l-dvb tree, best to keep it up-to-date.

included just everywhere
- remove dvb_i2c.[ch], it's not needed anymore
- rename dvb_register_frontend_new() to dvb_register_frontend()
-
|
|
|
|
- remove dvb i2c frontend (un)register code (all drivers use non-i2c frontend calls now)
- add i2c driver ids for all frontends to dvb_frontend.h (should be submitted to i2c-id.h)
- fix usage of i2c driver ids in dst, ves1x93, nxt6000 drivers
- remove dvb i2c functionality from av7110 and budget drivers
- remove dvb i2c functionality from Skystar2 driver
- fix up kernel Makefile
- add a FE_ATSC case to avoid compiler warning (print warning message instead)
|
|
|
|
- dvb_dummy_fe conversion to Kernel I2C
- Conversion from deprecated MODULE_PARM* to module_param*
- Adding/renaming existing *debug* parameter to debug.
- Common naming scheme for debug/I2C: dvbfe_*
|
|
- Remove module ref count changes to av7110 and budget-core,
as they did not do the right thing.
|
|
|
|
Note: this will probably break some of the drivers out there, which don't
register properly to the kernel i2c subsystem yet.
|
|
Also some minimal budget-ci CI support implemented (just detection+IRQs)
|
|
|
|
- fixed some return values in i2c device attach functions
|

Alan Cox reformatted the code to follow his coding style when
he fixed the merge bugs.
This patch now introduces these coding style changes, so
that we don't wipe out his changes with the next patchset.
|
|
- change some includes
|
|
|
|
less dependent on the linux kernel. here is the place to store
additional dvb_* functions, which encapsulate linux kernel functionality
which cannot be expressed as a one-liner
- rename ddelay() to dvb_delay(), move it to dvb_functions.h
- change all files to include dvb_functions.h instead of dvb_compat.h
- compile fix for the saa7111 driver
|

the version that made it into the 2.5.68 kernel.
- remove unnecessary c++-style comments
- fixed some line breaks and the style function headers
are formatted: please don't argue with me about these changes,
I don't care how they are formatted.
- remove newline breaks between memory allocation and the return value
check
Some more interesing stuff:
- remove ddelay() functions completly, replace with set_current_state() and
manual schedule_timeout() calls.
- made some init data for the mxb driver static and global (patch already
send to lkml)
Some crucial changes:
- inherit some return values Mr. Alan Cox has changed -- please review
|
|
- return POLL_ERR in case of filter timeout
