Subject: [PATCH] MFD: twl-core: move device_init_wakeup to after platform_device_add.
Date: Sat, 7 Jul 2012 08:51:03 +1000	[thread overview]
Message-ID: <20120707085103.7b1a51ec@notabene.brown> (raw)

[-- Attachment #1: Type: text/plain, Size: 1051 bytes --]



device_init_wakeup uses the dev_name() of the device to set the
name of the wakeup_source which appears in
/sys/kernel/debug/wakeup_sources.

For a platform device, that name is not set until platform_device_add
calls dev_set_name.

So the call to device_init_wakeup() must be after the call to
platform_device_add().
Making this change causes correct names to appear in the
wakeup_sources file.
