Subject: Warning with gpio-i2cmux
Date: Tue, 19 Apr 2011 17:25:01 +0200 [thread overview]
Message-ID: <20110419172501.5f37e46f@endymion.delvare> (raw)
Hi Peter,
I presume you are using gpio-i2cmux on some of your systems? I tried to
use it and I get the following warning when I rmmod the underlying I2C
controller driver:
WARNING: at drivers/base/core.c:143 device_release+0x82/0x90()
Hardware name: System Product Name
Device 'gpio-i2cmux.0' does not have a release() function, it is broken and must be fixed.
