2019-09-01leds: pwm: Use struct_size() helperGustavo A. R. Silva1-7/+1
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct led_pwm_priv { ... struct led_pwm_data leds[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes.

2019-07-25leds: core: Add support for composing LED class device namesJacek Anaszewski3-3/+145
Add generic support for composing LED class device name. The newly introduced led_compose_name() function composes device name according to either <color:function> or <devicename:color:function> pattern, depending on the configuration of initialization data. Backward compatibility with in-driver hard-coded LED class device names is assured thanks to the default_label and devicename properties of newly introduced struct led_init_data. In case none of the aforementioned properties was found, then, for OF nodes, the node name is adopted for LED class device name. At the occassion of amending the Documentation/leds/leds-class.txt unify spelling: colour -> color. Alongside these changes added is a new tool - tools/leds/get_led_device_info.sh. The tool allows retrieving details of a LED class device's parent device, which proves that using vendor or product name for devicename part of LED name doesn't convey any added value since that information had been already available in sysfs. The script performs also basic validation of a LED class device name.

2019-07-25leds: class: Improve LED and LED flash class registration APIJacek Anaszewski6-22/+26
Replace of_led_classdev_register() with led_classdev_register_ext(), which accepts easily extendable struct led_init_data, instead of the fixed struct device_node argument. The latter can be now passed in an fwnode property of the struct led_init_data. The modification is driven by the need for passing additional arguments required for the forthcoming generic mechanism for composing LED names. Currently the LED name is conveyed in the "name" char pointer property of the struct led_classdev. This is redundant since LED class device name is accessible throughout the whole LED class device life time via associated struct device's kobj->name property. The change will not break any existing clients since the patch alters also existing led_classdev{_flash}_register() macro wrappers, that pass NULL in place of init_data, which leads to using legacy name initialization path basing on the struct led_classdev's "name" property. Three existing users of devm_of_led_classdev_registers() are modified to use devm_led_classdev_register(), which will not impact their operation since they in fact didn't need to pass struct device_node on registration from the beginning.

For apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices. Therefore these boards don't need legacy support from this driver anymore. Both drivers claim the same device, so only one driver may exist in a system, putting distros in the position to decide between either apu2+ keys or apu1 led support.

2019-07-22leds: leds-lp5562 allow firmware files up to the maximum lengthNick Stoughton1-1/+5
Firmware files are in ASCII, using 2 hex characters per byte. The maximum length of a firmware string is therefore 16 (commands) * 2 (bytes per command) * 2 (characters per byte) = 64 Fixes: ff45262a85db ("leds: add new LP5562 LED driver") Signed-off-by: Nick Stoughton <nstoughton@logitech.com> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
2019-07-22leds: ns2: Add of_node_put() before returnNishka Dasgupta1-7/+14
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence create a new label, err_node_put, that puts the previous node before returning the required value. Edit the mid-loop return sites to instead go to this new label. Issue found with Coccinelle.

Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence create a new label, err_node_put, which puts the previous node and returns variable rv. Modify the mid-loop return statements to instead store the return value in rv and jump to err_node_put.
