Hi Bhaskar,
I think the commit subject "scripts: setlocalversion: fix shell syntax"
is strange. This patch does not fix any bug.
`some_command` works as well as $(some-command)
Please describe "what this commit does" in the commit subject,
and "why this change is needed" in the commit description.
An example of the subject would be:
scripts: setlocalversion: replace backquote to dollar parenthesis
An example of the commit description might be:
This commit improves the code readability.

This line is fine as-is.
