Subject: staging: unisys: remove unused locking functions in timskmod.h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fdee662e618250ef8c6ea10ad102c620af39f326;p=linux-beck.git

staging: unisys: remove unused locking functions in timskmod.h

Delete a block of unused locking functions from timskmod.h. These
functions generated a lot of checkpatch warnings and were not being used
anyhow.
