Prev: [PATCH 50/62] sysfs: Pack sysfs_dirent more tightly.
Next: [PATCH 54/62] sysfs: Kill unused sysfs_sb variable.
From: Greg Kroah-Hartman on 2 Mar 2010 18:40
From: Stephen Rothwell <sfr(a)canb.auug.org.au>

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/pci/pci-sysfs.c: In function 'pci_create_legacy_files':
drivers/pci/pci-sysfs.c:645: error: lvalue required as unary '&' operand
drivers/pci/pci-sysfs.c:658: error: lvalue required as unary '&' operand

Caused by commit "sysfs: Use sysfs_attr_init and sysfs_bin_attr_init on
dynamic attributes" interacting with commit "sysfs: Use one lockdep
class per sysfs attribute") both from the driver-core tree.
