From: Greg KH To: torvalds@osdl.org, akpm@osdl.org Cc: linux-kernel@vger.kernel.org Subject: [BK PATCH] Driver Core update for 2.6.4 Hi, Here are a few driver core changes for 2.6.3. They have all been in the -mm tree with the exception of the kref patch, which has been reviewed on lkml. These patches add a few more sysfs class entries, clean up the cdev interface and add the kref structure. Please pull from: bk://kernel.bkbits.net/gregkh/linux/driver-2.6 thanks, greg k-h p.s. I'll send these as patches in response to this email to lkml for those who want to see them. drivers/base/Makefile | 5 ++ drivers/base/bus.c | 4 - drivers/base/class.c | 16 ++++-- drivers/base/class_simple.c | 4 - drivers/base/core.c | 4 - drivers/base/driver.c | 4 - drivers/base/power/Makefile | 4 + drivers/base/power/main.c | 4 - drivers/base/power/shutdown.c | 4 - drivers/base/sys.c | 4 - drivers/char/drm/drm_stub.h | 35 +++++++++++++- drivers/char/lp.c | 16 +++++- drivers/char/misc.c | 1 drivers/char/tty_io.c | 80 ++++++++++++++++++--------------- drivers/ieee1394/amdtp.c | 3 - drivers/ieee1394/dv1394.c | 4 - drivers/ieee1394/raw1394.c | 4 - drivers/ieee1394/video1394.c | 3 - drivers/input/input.c | 4 + drivers/net/ppp_generic.c | 21 ++++++++ drivers/pci/hotplug/pci_hotplug_core.c | 14 ----- drivers/s390/char/tape_class.c | 7 -- drivers/scsi/sg.c | 7 +- drivers/scsi/st.c | 39 ++++++++++------ fs/char_dev.c | 26 +++------- include/linux/cdev.h | 4 - include/linux/kobject.h | 8 +++ include/linux/kref.h | 32 +++++++++++++ lib/Makefile | 3 + lib/kref.c | 60 ++++++++++++++++++++++++ net/netlink/netlink_dev.c | 20 +++++++- 31 files changed, 301 insertions(+), 143 deletions(-) ----- Andrew Morton: o cdev: warning fix Chris Wright: o class_simple cleanup in sg o class_simple cleanup in misc o class_simple cleanup in input o class_simple clean up in lp o Patch to hook up PPP to simple class sysfs support Greg Kroah-Hartman: o kref: add kref structure to kernel tree o remove cdev_set_name completely as it is not needed o PCI Hotplug: use the new decl_subsys_name() macro instead of rolling our own o Kobject: add decl_subsys_name() macro for users who want to set the subsystem name o Driver core: make CONFIG_DEBUG_DRIVER implementation a whole lot cleaner Jonathan Corbet: o cdev 2/2: hide cdev->kobj o cdev 1/2: Eliminate /sys/cdev Leann Ogasawara: o add sysfs simple class support for DRI char device o Fix class_register() always returns 0 o Add sysfs simple class support for netlink
