H Hartley Sweeten f425458eaf HID: Use module_hid_driver macro
Use the new module_hid_driver macro in all HID drivers that have
a simple register/unregister init/exit.

This also converts the hid drivers that test for a failure of
hid_register_driver() and report the failure. Using module_hid_driver
in those drivers removes the failure message.

Jiri Kosina 2f43f8749e HID: remove Paul Walmsley's copyright from places where it shouldn't be
Paul Walmsley has implemented dynamic quirk handling back in 2007 through
commits:

2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c")
8222fbe67c ("USB HID: clarify static quirk handling as squirks")
8cef908235 ("USB HID: add support for dynamically-created quirks")
876b9276b9 ("USB HID: add 'quirks' module parameter")

and as such, his copyright rightly belongs to
drivers/hid/usbhid/hid-quirks.c file.

However when generic HID code has been converted to bus and individual
quirks separated out to individual drivers on the bus, the copyright has
been blindly transfered into all the tiny drivers, which actually don't
contain any of Pauls' copyrighted code.

Remove the copyright from those sub-drivers.

Joe Perches 4291ee305e HID: Add and use hid_<level>: dev_<level> equivalents
Neaten current uses of dev_<level> by adding and using
hid specific hid_<level> macros.

Convert existing uses of dev_<level> uses to hid_<level>.
Convert hid-pidff printk uses to hid_<level>.

Remove err_hid and use hid_err instead.

Add missing newlines to logging messages where necessary.
Coalesce format strings.

Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt

Other miscellaneous changes:

Add const struct hid_device * argument to hid-core functions
extract() and implement() so hid_<level> can be used by them.
Fix bad indentation in hid-core hid_input_field function
that calls extract() function above.

Nikolai Kondrashov 73e4008ddd HID: allow resizing and replacing report descriptors
Update hid_driver's report_fixup prototype to allow changing report
descriptor size and/or returning completely different report descriptor.
Update existing usage accordingly.

This is to give more freedom in descriptor fixup and to allow having a whole
fixed descriptor in the code for the sake of readability.

Robert Schedel 3975bc5630 HID: Support 171 byte variant of Samsung USB IR receiver
Extends the existing Samsung USB IrDA (0419:0001) quirk with newly reported 171
byte variant. It needs the same quirk as the other devices already supported
by hid-samsung (wrong logical range)

Refactors duplicate trace call into local helper function.

The original bug report for the new variant is available at the second half of
this ticket page:

Robert Schedel 0810b51170 HID: Support new variants of Samsung USB IR receiver (0419:0001)
This patch extends the existing Samsung IrDA (0419:0001) quirk file with newly
reported variants:

* New device variants with 203 byte and 135 byte report descriptors were
  reported to be recognized incorrectly. This patch adds an autodetection for
  those two, using report descriptor size to enable new quirks.

* Any other unknown 0419:0001 variants will now be treated without any quirk
  flags (i.e. IGNORE_HIDINPUT/HIDDEV_FORCE will not be set by default anymore).

More details:

1. Descriptor size 184 bytes ("Satelco bundled remote")
Already supported since kernel 2.6.25 (my old patch).

2. Descriptor size 203 bytes ("Optronix remote")
This receiver mostly works with the regular HID input driver. Only when some
keys are released, another spurious key press event is interpreted due to
incorrect array ranges. According to HID 1.11, section 6.2.2.5, arrays should
return a 0 value when no control is asserted, and ranges should go from 1 to
the number of elements. The patch clips the value with a logical range from
1..15 (instead of originally 0..18).

Ticket with more information available at
https://bugs.launchpad.net/bugs/326986

3. Descriptor size 135 bytes ("Gotview remote")
This receiver has a similar issue than the previous one, i.e. it mostly works
with regular HID input, except some key press events get stuck on key release.
The patch clips the array value from 1..14 (instead of originally 0..17).

Ticket with more information available at
http://bugs.archlinux.org/task/15216

4. Other unknown variants (found one report with 218 bytes,
   but no further information about issues)

For such unknown variants we should refrain from changing any device flags.
Currently, HIDINPUT is suppressed and HIDDEV is enforced (because in 2.6.25 the
quirk table did not yet allow differentiating variants and we
did not expect variants either). Now we should be as strict as
possible and enable it only for the first variant above.

Jiri Slaby afa5eb7c68 HID: remove compat stuff
This removal was scheduled and there is no problem with later
distros to adapt for the new bus, thanks to aliases.

module-init-tools map files are deprecated nowadays, so that
the patch which introduced hid ones into the m-i-t won't be
accepted and hence there is no reason for leaving compat stuff in.
