Subject: proc: cleanup: remove unused assignments
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73d3646029138743989b6c213628484301a72eb1;p=linux-beck.git

proc: cleanup: remove unused assignments

I removed 3 unused assignments.  The first two get reset on the first
statement of their functions.  For "err" in root.c we don't return an
error and we don't use the variable again.
