This change is very good, thank you. The code continues from the original code(get_state_v1 and get_state_v2), didnât make any changes at that time, and sorry I have not seen linux-rockchip@xxxxxxxxxxxxxxxxxxx mail recently.

The way state->enabled is computed is rather convoluted and hard to
read - both branches of the if() actually do the exact same thing. So
remove the if(), and further simplify "<boolean condition> ? true :
false" to "<boolean condition>".

I stumbled on this while trying to understand how the pwm subsystem
works. This patch is a semantic no-op, but it's also possible that,
say, the first branch simply contains a "double negative" so either
the != should be == or the "false : true" should be "true : false".

I've applied this. Irrespective of any feedback David would have this is
correct and a nice simplification.
