Subject: [PATCH] of/address: Don't throw errors on absent ranges properties
Date: Fri, 14 Nov 2014 17:58:23 +1100 [thread overview]
Message-ID: <1415948303.666.50.camel@kernel.crashing.org> (raw)
The core always tries to translate any "reg" property to construct the platform
device names. This results in a pile of "OF: no ranges; cannot translate" errors
in dmesg whenever we expose things like i2c devices that cannot directly translate
to the MMIO space.
Turn this into a pr_debug instead
