Subject: Re: kernel error at led trigger "phy0tpt"
Hello,
the bisection gives following result:

18c7deca2b812537aa4d928900e208710f1300aa is the first bad commit
commit 18c7deca2b812537aa4d928900e208710f1300aa

soc: mediatek: pwrap: Use readx_poll_timeout() instead of custom
function
Function pwrap_wait_for_state() is a function that polls an address
through a helper function, but this is the very same operation that
the readx_poll_timeout macro means to do.
Convert all instances of calling pwrap_wait_for_state() to instead
use the read_poll_timeout macro.
