There are only a few changes for the 5.17 cycle: a fix for missing
colons in the comments of struct counter_comp, a minor improvement in
the access of private data in the ti-eqep driver, and bug fix for the
interrupt enablement code of the 104-quad-8 driver. Due to the small
number of patches, the respective changes are submitted here as a patch
series.

  counter: ti-eqep: Use container_of instead of struct
    counter_device::priv

William Breathitt Gray (1):
  counter: 104-quad-8: Fix persistent enabled events bug

Yanteng Si (1):
  counter: Add the necessary colons and indents to the comments of
    counter_compi

Using counter->priv is a memory read and so more expensive than
container_of which is only an addition. (In this case even a noop
because the offset is 0.)

So container_of is expected to be a tad faster, it's type-safe, and
produces smaller code (ARCH=arm allmodconfig):

A bug exists if the user executes a COUNTER_ADD_WATCH_IOCTL ioctl call,
and then executes a COUNTER_DISABLE_EVENTS_IOCTL ioctl call. Disabling
the events should disable the 104-QUAD-8 interrupts, but because of this
bug the interrupts are not disabling.

The reason this bug is occurring is because quad8_events_configure() is
called when COUNTER_DISABLE_EVENTS_IOCTL is handled, but the
next_irq_trigger[] array has not been cleared before it is checked in
the loop.

This patch fixes the bug by removing the next_irq_trigger array and
instead utilizing a different algorithm of walking the events_list list
for the current requested events. When a COUNTER_DISABLE_EVENTS_IOCTL is
handled, events_list will be empty and thus all device channels end up
with interrupts disabled.
