2023-01-21iio: light: vcnl4000: Make irq handling more genericMårten Lindahl
This driver supports 4 chips, by which only one (vcnl4010) handles interrupts and has support for triggered buffer. The setup of these functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe, and thus ignores the chip specific configuration structure where all other chip specific functions are specified. This complicates adding interrupt handler and triggered buffer support to chips which may have support for it. Add members for irq threads and iio_buffer_setup_ops to the generic vcnl4000_chip_spec struct, so that instead of checking a chip specific boolean irq support, we check for a chip specific triggered buffer handler, and/or a chip specific irq thread handler.

The sensor is operating in continuous measurement mode and changes to sleep mode if not used for 5 seconds.

2022-12-25treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
