leds: turris-omnia: check for LED_COLOR_ID_RGB instead LED_COLOR_ID_MULTI

2020-11-25T12:25:28+00:00

LED core does not allow LED_COLOR_ID_MULTI for now and instead for RGB
LEDs prefers LED_COLOR_ID_RGB.

leds: turris-omnia: fix checkpatch warning

2020-11-25T12:25:27+00:00

Use kstrtoul instead of sscanf to satisfy checkpatch.

leds: turris-omnia: wrap to 80 columns

2020-11-25T12:25:27+00:00

Although checkpatch changed the max-line-length default to 100 columns,
we still prefer 80 columns somewhere.

leds: turris-omnia: use constants instead of macros for color command

2020-11-25T12:25:27+00:00

Use integer constants directly when building I2C messages for LED color
change command, instead of macros. The command is simple enough to
understand what is going on even without these names.

leds: lp50xx: Fix an error handling path in 'lp50xx_probe_dt()'

2020-11-25T12:18:20+00:00

In case of memory allocation failure, we must release some resources as
done in all other error handling paths of the function.

'goto child_out' instead of a direct return so that 'fwnode_handle_put()'
is called when we break out of a 'device_for_each_child_node' loop.

leds: netxbig: add missing put_device() call in netxbig_leds_get_of_pdata()

2020-11-25T12:18:08+00:00

if of_find_device_by_node() succeed, netxbig_leds_get_of_pdata() doesn't
have a corresponding put_device(). Thus add jump target to fix the
exception handling for this function implementation.

leds: pwm: Remove platform_data support

2020-10-07T10:02:58+00:00

Since commit 141f15c66d94 ("leds: pwm: remove header") that platform
interface is not usable from outside and there seems to be no in tree
user anymore.  All in-tree users of the leds-pwm driver seem to use DT
currently.  Getting rid of the old platform interface allows the
leds-pwm driver to switch over from 'devm_led_classdev_register()' to
'devm_led_classdev_register_ext()'.

leds: lm3697: Fix out-of-bound access

2020-10-05T18:36:09+00:00

If both LED banks aren't used in device tree, an out-of-bounds
condition in lm3697_init occurs because of the for loop assuming that
all the banks are used.  Fix it by adding a variable that contains the
number of used banks.

leds: ns2: do not guard OF match pointer with of_match_ptr

2020-09-30T17:22:58+00:00

Do not match OF match pointer with of_match_ptr, so that even if
CONFIG_OF is disabled, the driver can still be bound via another method.

Move definition of of_ns2_leds_match just before ns2_led_driver
definition, since it is not needed sooner.

leds: ns2: convert to fwnode API

2020-09-30T17:22:58+00:00

Convert from OF api to fwnode API, so that it is possible to bind this
driver without device-tree.

The fwnode API does not expose a function to read a specific element of
an array. We therefore change the types of the ns2_led_modval structure
so that we can read the whole modval array with one fwnode call.
