Subject: kbuild: fix adjust_autoksyms.sh for modules that need only one symbol
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a7c65b9729e4a5e9c0809784bc52466b0dbaafa7;p=linux-beck.git

kbuild: fix adjust_autoksyms.sh for modules that need only one symbol

When only one symbol was listed and therefore the line didn't contain
any space to separate multiple symbols, that symbol got ignored.
