Subject: [PATCH v2 00/24] hrtimers: Consolidate hrtimer initialization - Part 3

hrtimers is initialized with hrtimer_init(), and after that the timer's
callback function is setup separately. This separate initialization is
error prone and awkward to use.

hrtimer_setup() combines the initialization and is simpler to use.

Switch to use the new setup function. Most conversions were done with
Coccinelle, see the sematic patch below.

This series is intended to be applied to the tip tree.

v1 -> v2 https://lore.kernel.org/lkml/cover.1729865232.git.namcao@linutronix.de
  - rebase to v6.14-rc1
  - use the existing hrtimer_dummy_timeout() for rt2x00 driver and bcm driver
