Subject: staging: flexfb: Remove initialization to 0
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=462125b4ad255eafcd114e17bdc924d755da1567;p=linux-beck.git

staging: flexfb: Remove initialization to 0

(the initial post had a typo in the short summary, reposting)

This fixes some of the code style issues in the flexfb driver by removing
unnecessary initializations of static variables to 0 or to NULL.
