[PATCH v3 00/15] lirc_dev fixes and beautification

[Andi Shyti]

Hi,

This is a collection of fixes, added functionality, coding rework
and trivial coding style fixes.

The first patch is preparatory to the second, which allows the
user to create a lirc driver without receiver buffer, which is
obvious for transmitters.

The rest of the patches is a series of coding style and code
rework, as I said, some of them are very trivial, but I sent them
anyway because I was on fire.

Patch 14 is a segfault fix, while the last patch adds the
possibility to send to ioctl the set frequency, get frequency and
set length command.

Changelog:

V1 -> V2
 - patch 4: added the pr_fmt definition and removed all the
   hardcoded prefixes from the pr_* functions (from Joe Perches).

 - patch 15: removed the definitions of the GET/SET_FREQUENCY, I
   will use GET/SET_SEND_CARRIER instead, even though I find the
   name a bit confusing (from Sean Young).

 - In patch 6 I did a better refactoring

V2 -> V3
 - patch 2: do not create a specific function for bufferless
   allocation, but check whether the device is a transmitter, in
   that case do not allocate any buffer (from Sean Young).

 - patch 10: remove completely compat ioctl (from Hans Verkuil).

 - patch 12: ioctl fails and returns -ENOTTY instead of -EPERM
   (from Hans Verkuil).

 - patch 15: removed the original patch which adds the
   LIRC_GET_LENTGH command to the ioctl (from Sean Young).

 - patch 15: new patch which uses LIRC_CAN_REC() define to check
   if the device is a receiver.

Thanks,
Andi
