Merge tag 'leds-for-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski: "LED core fixes and improvements: - avoid races with workqueue - Kconfig: pedantic cleanup - small fixes for Flash class description leds-lt3593: - remove unneeded assignment in lt3593_led_probe - drop pdata handling code leds-blinkm: - clean up double assignment to data->i2c_addr leds-pca955x, leds-pca963x: - revert ACPI support, as it turned out that there is no evidence of officially registered ACPI IDs for these devices. - make use of device property API leds-as3645a: - switch to fwnode property API LED related addition to ACPI documentation: - document how to refer to LEDs from remote nodes LED related fix to ALSA line6/toneport driver: - avoid polluting led_* namespace And lm3532 driver relocation from MFD to LED subsystem, accompanied by various improvements and optimizations; it entails also a change in omap4-droid4-xt894.dts: - leds: lm3532: Introduce the lm3532 LED driver - mfd: ti-lmu: Remove LM3532 backlight driver references - ARM: dts: omap4-droid4: Update backlight dt properties - dt: lm3532: Add lm3532 dt doc and update ti_lmu doc" * tag 'leds-for-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: leds: avoid races with workqueue ALSA: line6: Avoid polluting led_* namespace leds: lm3532: Introduce the lm3532 LED driver mfd: ti-lmu: Remove LM3532 backlight driver references ARM: dts: omap4-droid4: Update backlight dt properties dt: lm3532: Add lm3532 dt doc and update ti_lmu doc leds: Small fixes for Flash class description leds: blinkm: clean up double assignment to data->i2c_addr leds: pca963x: Make use of device property API leds: pca955x: Make use of device property API leds: lt3593: Remove unneeded assignment in lt3593_led_probe leds: lt3593: drop pdata handling code leds: pca955x: Revert "Add ACPI support" leds: pca963x: Revert "Add ACPI support" drivers: leds: Kconfig: pedantic cleanups ACPI: Document how to refer to LEDs from remote nodes leds: as3645a: Switch to fwnode property API
