Subject: [PATCH -next] v4l2: handle unregister for non-I2C builds
Date: Mon, 11 May 2009 09:37:41 -0700	[thread overview]
Message-ID: <4A085455.5040108@oracle.com> (raw)
In-Reply-To: <20090511161442.3e9d9cb9.sfr@canb.auug.org.au>

From: Randy Dunlap <randy.dunlap@oracle.com>

Build fails when CONFIG_I2C=n, so handle that case in the if block:

drivers/built-in.o: In function `v4l2_device_unregister':
(.text+0x157821): undefined reference to `i2c_unregister_device'
