[media] media: radio-si4713: improve usage of gpiod API

2015-04-08T09:40:33+00:00

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Simplify accordingly.

Moreover use the _optional variant which has tighter error checking, but
is simpler to use which allows further simplification.

[media] wl128x: embed video_device

2015-04-03T02:35:52+00:00

Embed the video_device struct to simplify the error handling and in
order to (eventually) get rid of video_device_alloc/release.

[media] wl128x-radio really depends on TI_ST

2015-04-02T21:23:28+00:00

All other drivers using the TI_ST infrastructure use
'depends on' for this symbol, and it makes no sense
to only enable that if CONFIG_NET is enable, because
the radio driver also depends on CONFIG_NET itself:

ERROR: "skb_queue_purge" [drivers/media/radio/wl128x/fm_drv.ko] undefined!
ERROR: "skb_push" [drivers/media/radio/wl128x/fm_drv.ko] undefined!
ERROR: "skb_pull" [drivers/media/radio/wl128x/fm_drv.ko] undefined!

Making the driver dependency explicit solves randconfig
build problems and makes it more obvious to the reader.

[media] media: radio: assign wait_for_completion_timeout to appropriately typed var

2015-03-02T19:49:58+00:00

wait_for_completion_timeout() returns unsigned long not int. This assigns
the return value to an appropriately typed variable (also helps keep
static code checkers happy).

[media] si470x: fixup wait_for_completion_timeout return handling

2015-03-02T17:55:44+00:00

return type of wait_for_completion_timeout is unsigned long not int. A
appropriately named variable of type unsigned long is added and the
assignments fixed up.

[media] radio/aimslab: use mdelay instead of udelay

2015-02-02T13:07:09+00:00

Large udelay values are not allowed on the ARM architecture
and result in a build error like

ERROR: "__bad_udelay" [drivers/media/radio/radio-aimslab.ko] undefined!

This changes the aimslab radio driver to use an equivalent mdelay
statement.

[media] media: radio: wl128x: fmdrv_rx.c: Remove unused function

2015-01-27T11:56:20+00:00

Remove the function fm_rx_get_rds_system() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"
