Subject: [PATCH v2 0/6] Introduce deferred probing
Date: Wed, 15 Apr 2015 00:53:14 +0200	[thread overview]
Message-ID: <1429052000-20647-1-git-send-email-sebastian.hesselbarth@gmail.com> (raw)

This is round two of the introduction of deferred probing by moving
drivers that request probe deferral to an extra device list that will
be re-probed later.

Compared to v1 there are the following changes:
- Loop over deferred device list until none succeeds
  (Suggested by Sascha Hauer)
- (Now) properly deal with deferred probing in led-gpio
- Free GPIOs claimed by leds on foo_led_unregister()
- Convert Orion GPIO to real platform driver
Each patch also contains an individual changelog.

It would be great to give this patch series a little more coverage.
Also, several other subsystems could use some support -EPROBE_DEFER
but IMHO we should wait for someone to actually force probe deferral
there.
