Subject: [PATCH 0/8] counter: Remove struct counter_device::priv

Hello,

similar to patch
https://lore.kernel.org/r/4bde7cbd9e43a5909208102094444219d3154466.1640072891.git.vilhelm.gray@gmail.com
the usage of struct counter_device::priv can be replaced by
container_of which improves type safety and code size.

This series depends on above patch, converts the remaining drivers and
finally drops struct counter_device::priv.

This series was compile tested using ARCH=arm allmodconfig with the
following change:

 config 104_QUAD_8
        tristate "ACCES 104-QUAD-8 driver"
-       depends on PC104 && X86
+       depends on PC104 && X86 || COMPILE_TEST
        select ISA_BUS_API

in drivers/counter/Kconfig.

Best regards
Uwe
