Subject: [PATCH -next] driver core: fix build for CONFIG_BLOCK not enabled
Date: Fri, 24 Sep 2010 14:36:49 -0700	[thread overview]
Message-ID: <20100924143649.59f0572a.randy.dunlap@oracle.com> (raw)
In-Reply-To: <20100924145537.bd092bfb.sfr@canb.auug.org.au>

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

Fix build errors when CONFIG_BLOCK is not enabled:

drivers/base/core.c: In function 'get_device_parent':
drivers/base/core.c:634: error: 'block_class' undeclared (first use in this function)
drivers/base/core.c: In function 'device_add_class_symlinks':
drivers/base/core.c:723: error: 'block_class' undeclared (first use in this function)
drivers/base/core.c: In function 'device_remove_class_symlinks':
drivers/base/core.c:751: error: 'block_class' undeclared (first use in this function)
