X-Git-Tag: v4.16~17^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=1b8837b61714c3743fadb3a6bbb57ffd53839e7c;p=linux.git

ARM: 8750/1: deflate_xip_data.sh: minor fixes

Send nm complaints about broken pipe (when sed exits early) to /dev/null.
All errors should be printed to stderr.
Don't trap on normal exit so the trap can return an error code.
