      [media] dib8000: rename dib8000_attach to dib8000_init · b9bc7d59
      由 Mauro Carvalho Chehab 提交于 
      Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.

It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.

dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
  given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
  doesn't print who loaded the module);
- after loading the module, it runs the function associated
  with the dynamic symbol.

When compiled as builtin, it just calls the function given to it.

As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.

In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.

We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

      [media] dib7000: export just one symbol · 8abe4a0a
      由 Mauro Carvalho Chehab 提交于 
      Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

This were reported several times, like:

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_tuner_attach':
>> cxusb.c:(.text+0x27d4b5): undefined reference to `dib7000p_get_i2c_master'
   drivers/built-in.o: In function `dib7070_set_param_override':
   cxusb.c:(.text+0x27d5a5): undefined reference to `dib0070_wbd_offset'
>> cxusb.c:(.text+0x27d5be): undefined reference to `dib7000p_set_wbd_ref'
   drivers/built-in.o: In function `dib7070_tuner_reset':
>> cxusb.c:(.text+0x27d5f9): undefined reference to `dib7000p_set_gpio'
   drivers/built-in.o: In function `cxusb_dualdig4_rev2_frontend_attach':
>> cxusb.c:(.text+0x27df5c): undefined reference to `dib7000p_i2c_enumeration'

In this specific report:
	CONFIG_DVB_USB_CXUSB=y
	CONFIG_DVB_DIB7000P=m

But the same type of bug can happen if:
	CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).

As a bonus, dib7000p won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with Hauppauge Nova-TD (2 frontends).

      [media] dib7000p: rename dib7000p_attach to dib7000p_init · 7f67d96a

For almost all DVB frontends, there's just one function.

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename the function that probes and init the hardware
to dib7000p_init.

A latter patch will add a new dib7000p_attach that will be
used as originally conceived by dvb_attach() way.

      [media] dvbdev: add a dvb_detach() macro · 4647f487
      由 Mauro Carvalho Chehab 提交于 
      The dvb_attach() was unbalanced, as there was no dvb_dettach. Ok,
on current cases, the dettach is done by dvbdev, but that are some
future corner cases where we may need to do this before registering
the frontend.

So, add a dvb_detach() and use it at dvb_frontend.c.

      [media] lmedm04: rs2000 check if interrupt urb is over due · 3a370222
      由 Malcolm Priestley 提交于 
      Change handling of signal_lock on rs2000. Use ibuf[2] to detect
lock as there is a longer wait for lock to appear in ibuf[6].

Remove last_key and key_timeout and use jiffies plus 60ms
to detect that streaming is still active.

If the current jiffies is time_after the interrupt urb overdue and
clear signal lock.

This results in far faster recovery of lock and streaming.

      [media] media: davinci: vpif_capture: drop unneeded module params · 4015bef6
      由 Lad, Prabhakar 提交于 
      Remove bogus 'numbuffers' and 'bufsize' module options. The number of buffers and
buffer sizes are determined by VIDIOC_REQBUFS and VIDIOC_S_FMT and the amount of
available memory (in the case of the MMAP stream I/O mode) and not by module
options.

These module params are a left-over from the original montavista code that used
these parameters to pre-allocate the memory needed for the buffers. The code that
allocated those buffers was never upstreamed since by the time the drivers were
added to the kernel the TI cmem module could be used in combination with the
USERPTR mode to reserve and pass physically contiguous memory pointers around.

These days of course CMA is used instead of cmem.

This patch removes these module options altogether since they no longer do what
they originally were designed for. They should never have been part of the
upstreamed code in the first place, so they've been pointless ever since
2.6.32 when this driver first appeared in the mainline kernel.
