Subject: [PATCH v1 00/28] leds: cleanups and fwnode refcounting bug fixes

When analyzing the current state of affairs with fwnode reference counting 
I found that a lot of core doesn't take it right. Here is a bunch of
corresponding fixes against LED drivers.

The series includes some cleanups and a few other fixes grouped by a driver.

First two patches are taking care of -ENOTSUPP error code too  prevent its
appearance in the user space.

Andy Shevchenko (28):
  leds: class: The -ENOTSUPP should never be seen by user space
  leds: core: The -ENOTSUPP should never be seen by user space
  leds: el15203000: Give better margin for usleep_range()
  leds: el15203000: Make error handling more robust
  leds: el15203000: Correct headers (of*.h -> mod_devicetable.h)
  leds: el15203000: Introduce to_el15203000_led() helper
  leds: lgm-sso: Fix clock handling
  leds: lgm-sso: Put fwnode in any case during ->probe()
  leds: lgm-sso: Don't spam logs when probe is deferred
  leds: lgm-sso: Remove unneeded of_match_ptr()
  leds: lgm-sso: Remove explicit managed resource cleanups
  leds: lgm-sso: Drop duplicate NULL check for GPIO operations
  leds: lgm-sso: Convert to use list_for_each_entry*() API
  leds: lm3532: select regmap I2C API
  leds: lm3532: Make error handling more robust
  leds: lm36274: Put fwnode in error case during ->probe()
  leds: lm36274: Correct headers (of*.h -> mod_devicetable.h)
  leds: lm3692x: Put fwnode in any case during ->probe()
  leds: lm3692x: Correct headers (of*.h -> mod_devicetable.h)
  leds: lm3697: Update header block to reflect reality
  leds: lm3697: Make error handling more robust
  leds: lm3697: Don't spam logs when probe is deferred
  leds: lp50xx: Put fwnode in error case during ->probe()
  leds: lt3593: Put fwnode in any case during ->probe()
  leds: lt3593: Make use of device properties
  leds: pwm: Make error handling more robust
  leds: rt8515: Put fwnode in any case during ->probe()
  leds: sgm3140: Put fwnode in any case during ->probe()
