[PATCH v7 4/8] mac_oldworld: Drop some variables |
Date: |
Mon, 29 Jun 2020 20:55:26 +0200 |
Values not used frequently enough may not worth putting in a local
variable, especially with names almost as long as the original value
because that does not improve readability, to the contrary it makes it
harder to see what value is used. Drop a few such variables.
