Why do you declare this (and other module-local) function as inline?
It is usually better let compiler decide if given function should be
inlined or not.

fpc->lock will be used while pwmchip_remove() is running so you should
not be destroying it before calling pwmchip_remove(). It should probbaly
go into free() method or just drop it altogether.
