scripts/spelling.txt: add "intialization" pattern and fix typo instances

2017-02-28T02:43:47Z

Fix typos and add the following to the scripts/spelling.txt: intialization||initialization The "inintialization" in drivers/acpi/spcr.c is a different pattern but I fixed it as well in this commit.

firewire: core: document fw_csr_string's truncation of long strings

2014-12-10T19:53:02Z

fw_csr_string() truncates and terminates target strings like strlcpy() does. Unlike strlcpy(), it returns the target strlen, not the source strlen, hence users of fw_csr_string() are unable to detect truncation. Point this behavior out in the kerneldoc comment.

firewire: don't use PREPARE_DELAYED_WORK

2014-03-07T15:19:57Z

PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. firewire core-device and sbp2 have been been multiplexing work items with multiple work functions. Introduce fw_device_workfn() and sbp2_lu_workfn() which invoke fw_device->workfn and sbp2_logical_unit->workfn respectively and always use the two functions as the work functions and update the users to set the ->workfn fields instead of overriding work functions using PREPARE_DELAYED_WORK(). This fixes a variety of possible regressions since a2c1c57be8d9 "workqueue: consider work function when searching for busy work items" due to which fw_workqueue lost its required non-reentrancy property.

firewire: remove support of fw_driver.driver.probe and .remove methods

After all IEEE 1394 high-level drivers being converted to bus-specific .probe/.remove methods, remove support of the obsolete generic methods. Signed-off-by: Stefan Richter

firewire: introduce fw_driver.probe and .remove methods

2013-06-09T16:15:00Z

FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.

firewire: remove unnecessary alloc/OOM messages

These are redundant to log messages from the mm core. Signed-off-by: Stefan Richter

firewire: convert to idr_alloc()

2013-02-28T03:10:15Z

Convert to the much saner new idr interface. v2: Stefan pointed out that add_client_resource() may be called from non-process context. Preload iff @gfp_mask contains __GFP_WAIT. Also updated to include minor upper limit check.

firewire: add minor number range check to fw_device_init()

firewire: core: add is_local sysfs device attribute

2012-06-30T08:49:06Z

Making this information available in sysfs allows to differentiate between controllers in the local and remote Linux PCs, and thus is useful for servers that are started with udev rules. Signed-off-by: Clemens Ladisch Signed-off-by: Stefan Richter
