Subject: [PATCH v2] staging: gasket: fix indentation and lines ending with open parenthesis
This patch fixes warnings of 'checkpatch.pl'. According to
Linux coding guidelines, code should be aligned properly to
match with open parenthesis and lines should not end with
open parenthesis.
Signed-off-by: Mahak Gupta <gmahak1@...il.com>

Changes since v1:
- Use temporary variables to shorten long lines. This variable was used multiple times.
