treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

firewire: core: replace IDR with XArray to maintain fw_device

2024-08-12T01:42:50+00:00

In core function, the instances of fw_device corresponding to firewire device
node in system are maintained by IDR. As of kernel v6.0, IDR has been
superseded by XArray and deprecated.

This commit replaces the usage of IDR with XArray to maintain the device
instances. The instance of XArray is allocated statically, and
initialized with XA_FLAGS_ALLOC so that the index of allocated entry starts
with zero and available as the minor identifier of device node.

firewire: core: use guard macro to maintain properties of fw_card

2024-08-05T08:54:05+00:00

The core functions uses spinlock in instance of fw_card structure to
protect concurrent access to properties in the instance.

This commit uses guard macro to maintain the spinlock.

firewire: core: use guard macro to maintain list of asynchronous transaction

2024-08-05T08:54:04+00:00

The core function maintains pending asynchronous transactions by list in
the instance of fw_card. The concurrent access to the list is protected
by spinlock in the instance.

This commit uses guard macro to maintain the spinlock.

firewire: core: use guard macro to maintain the list of address handler for transaction

2024-08-05T08:53:58+00:00

The core function maintains address handlers by list. It is protected by
spinlock to insert and remove entry to the list.

This commit uses guard macro to maintain the spinlock.

firewire: core: use guard macro to maintain RCU scope for transaction address handler

2024-08-05T08:53:56+00:00

The core function maintains address handlers by list. RCU is utilized
for efficient read access to any entries in the list.

This commit uses guard macro to maintain RCU locking and releasing.

firewire: core: use guard macro to maintain static packet data for phy configuration

2024-08-05T08:53:52+00:00

The core function provide a kernel API to send phy configuration packet.
Current implementation of the feature uses packet object allocated
statically. The concurrent access to the object is protected by static
mutex.

This commit uses guard macro to maintain the mutex.

firewire: core: use common helper function to serialize phy configuration packet

2024-07-29T13:46:31+00:00

A common helper function is available to serialize the first quadlet of phy
configuration packet.

This commit is for the purpose.
