leds: turn the blink_timer off before starting to blink

2011-11-11T17:42:34+00:00

commit 488bc35bf40df89d37486c1826b178a2fba36ce7 upstream.

Depending on the implementation of the hardware blinking function in
blink_set(), the led can support hardware blinking for some values of
delay_on and delay_off and fall-back to software blinking for some other
values.

Turning off the blink_timer unconditionally before starting to blink
make sure that a sequence like:

  OFF
  hardware blinking
  software blinking
  hardware blinking

does not leave the software blinking timer active.

leds: save the delay values after a successful call to blink_set()

2011-11-11T17:42:34+00:00

commit 6123b0e274503a0d3588e84fbe07c9aa01bfaf5d upstream.

When calling the hardware blinking function implemented by blink_set(),
the delay_on and delay_off values are not preserved across calls.

Fix that and make the "timer" trigger work as expected when hardware
blinking is available.

BEFORE the fix:
  $ cd /sys/class/leds/someled
  $ echo timer > trigger
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_on
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_off
  $ cat delay_on delay_off
  0
  0

AFTER the fix:
  $ cd /sys/class/leds/someled
  $ echo timer > trigger
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_on
  $ cat delay_on delay_off
  100
  0
  $ echo 100 > delay_off
  $ cat delay_on delay_off
  100
  100

drivers/leds/ledtrig-timer.c: fix broken sysfs delay handling

2011-09-15T01:09:38+00:00

Fix regression introduced by commit 5ada28bf7675 ("led-class: always
implement blinking") which broke sysfs delay handling by not storing the
updated value.  Consequently it was only possible to set one of the delays
through the sysfs interface as the other delay was automatically restored
to it's default value.  Reading the parameters always gave the defaults.

drivers/leds/leds-netxbig: make LEDS_NETXBIG depend on LEDS_CLASS

2011-07-26T03:57:15+00:00

We call led_classdev_register/led_classdev_unregister in
create_netxbig_led/delete_netxbig_led, thus make LEDS_NETXBIG depend on
LEDS_CLASS.

This patch fixes below build error if LEDS_CLASS is not configured.
