leds: ktd2692: Set missing timing properties

2024-12-05T13:02:10+00:00

[ Upstream commit 95c65546f03f888481eda98b499947252e1f3b20 ]

props.timing is not set after commit b5a8c50e5c18 ("leds: ktd2692: Convert
to use ExpressWire library"). Set it with ktd2692_timing.

leds: max5970: Fix unreleased fwnode_handle in probe function

2024-12-05T13:02:10+00:00

[ Upstream commit 02f58f97419c828f58e30f24f54395ac9be159c0 ]

An object initialized via device_get_named_child_node() requires calls
to fwnode_handle_put() when it is no longer required to avoid leaking
memory.

Add the automatic cleanup facility for 'led_node' to ensure that
fwnode_handle_put() is called in all execution paths.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do
	sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i
done
git mv include/asm-generic/unaligned.h include/linux/unaligned.h
git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43+00:00

no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

leds: turris-omnia: Fix module autoloading with MODULE_DEVICE_TABLE()

Add MODULE_DEVICE_TABLE(), so modules could be properly autoloaded
based on the alias from of_device_id table.

leds: pca9532: Remove irrelevant blink configuration error message

2024-08-30T08:01:08+00:00

The update_hw_blink() function prints an error message when hardware is
not able to handle a blink configuration on its own. IMHO, this isn't a
'real' error since the software fallback is used afterwards.

Remove the error messages to avoid flooding the logs with unnecessary
messages.

leds: gpio: Set num_leds after allocation

2024-08-23T07:40:43+00:00

With the new __counted_by annotation, the "num_leds" variable needs to
valid for accesses to the "leds" array. This requirement is not met in
gpio_leds_create(), since "num_leds" starts at "0", so "leds" index "0"
will not be considered valid (num_leds would need to be "1" to access
index "0").

Fix this by setting the allocation size after allocation, and then update
the final count based on how many were actually added to the array.

leds: lp55xx: Use devm_clk_get_enabled() helpers

2024-08-22T13:48:24+00:00

Simplify the code a bunch by using managed resource helpers.

Also, there is no need to save clk pointer anymore.

leds: as3645a: Use device_* to iterate over device child nodes

2024-08-22T13:48:02+00:00

Drop the manual access to the fwnode of the device to iterate over its
child nodes. `device_for_each_child_node` macro provides direct access
to the child nodes, and given that the `child` variable is only required
within the loop, the scoped variant of the macro can be used.

Use the `device_for_each_child_node_scoped` macro to iterate over the
direct child nodes of the device.
