[GIT PULL 10/22] intel_th: msu: Replace open-coded list_{first,last,next}_entry variants

From: Alexander Shishkin
Date: Fri May 03 2019 - 04:46:05 EST


There are a few places in the code where open-coded versions of list entry
accessors list_first_entry()/list_last_entry()/list_next_entry() are used.

Replace those with the standard macros.
