From: Varka Bhadram <var...@cdac.in>
This patch fix the following spacing issues:
no space before tabs
space required after that ';'
space required before the open parenthesis '(
space prohibited before that ':' (ctx:WxE)
space prohibited before that close parenthesis ')'
no spaces at the start of a line
