Pull driver core patches from Greg KH: "Here's the big driver core pull request for 3.12-rc1. Lots of tiny changes here fixing up the way sysfs attributes are created, to try to make drivers simpler, and fix a whole class race conditions with creations of device attributes after the device was announced to userspace. All the various pieces are acked by the different subsystem maintainers" * tag 'driver-core-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (119 commits) firmware loader: fix pending_fw_head list corruption drivers/base/memory.c: introduce help macro to_memory_block dynamic debug: line queries failing due to uninitialized local variable sysfs: sysfs_create_groups returns a value. debugfs: provide debugfs_create_x64() when disabled rbd: convert bus code to use bus_groups firmware: dcdbas: use binary attribute groups sysfs: add sysfs_create/remove_groups for when SYSFS is not enabled driver core: add #include to core files.

regmap: debugfs: Fix continued read from registers file

2013-08-28T17:27:08Z

The regmap_debugfs_get_dump_start() function maps from a file offset to the register that can be found at that position in the file. This is done using a look-up table. Commit d6814a7d ("regmap: debugfs: Suppress cache for partial register files") added a check to bypass the look-up table for partial register files, since the offsets in that table are only correct for the full register file. The check incorrectly uses the file offset instead of the register base address and returns it. This will cause the file offset to be interpreted as a register address which will result in a incorrect output from the registers file for all reads except at position 0. The issue can easily be reproduced by doing small reads the registers file, e.g. `dd if=registers bs=10 count=5`.

driver core: replace strict_strto() with kstrto()

2013-07-27T01:02:43Z

The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman

regmap: debugfs: Suppress cache for partial register files

2013-06-19T09:18:09Z

The cache is based on the full register map so confuses things if used for a partial map. Reported-by: Bard Liao Signed-off-by: Mark Brown

regmap: debugfs: Fix return from regmap_debugfs_get_dump_start

2013-05-14T12:53:45Z

regmap_debugfs_get_dump_start should return the offset of the register it should start reading from, However in the current code at one point the code does not return correct register offset. With this patch all the returns from this function takes reg_stride in to consideration to return correct offset. Signed-off-by: Srinivas Kandagatla Signed-off-by: Mark Brown

regmap: debugfs: Don't mark lockdep as broken due to debugfs write

2013-05-12T15:01:39Z

A register write to hardware is reasonably unlikely to cause locking dependency issues, the reason we're tainting is that unexpected changes in the hardware configuration may confuse drivers. Signed-off-by: Mark Brown

regmap: debugfs: Add a registers `range' file

2013-03-04T02:33:03Z

This file lists the register ranges in the register map. The condition to split the range is based on whether the block is readable or not. Ensure that we lock the `debugfs_off_cache' list whenever we access and modify the list. There is a possible race otherwise between the read() operations of the `registers' file and the `range' file.
