What parse issue ? Please expand this part of the commit message.

Basically if this is not MP13, and the dev_dbg() is hit, the function 
should not return error code because for non-MP13 the missing syscfg 
phandle in DT is not considered an error. So reset err to 0 in that case 
to support existing DTs without syscfg phandle.
