scripts/mksysmap: Fix badly escaped '$'
The backslash characters escaping '$' in the command to sed (intended to prevent it from interpreting '$' as "end-of-line") are currently being consumed by the Shell (where they mean that sh should not evaluate what follows '$' as a variable name). This means that sed -e "/ \$/d" executes the script / $/d instead of the intended / \$/d So escape twice in mksysmap any '$' that actually needs to reach sed escaped so that the backslash survives the Shell. Fixes: c4802044a0a7 ("scripts/mksysmap: use sed with in-line comments") Fixes: 320e7c9d4494 ("scripts/kallsyms: move compiler-generated symbol patterns to mksysmap") Signed-off-by: Pierre-Clément Tosi <ptosi@google.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
