[PATCH] coverity: fs/ext3/super.c: match_int return check
The return value of "match_int" is checked 27 out of 28 times
In lib/parser.c
142 /**
143 * match_int: - scan a decimal representation of an integer from a substring_t
144 * @s: substring_t to be scanned
145 * @result: resulting integer on success
146 *
147 * Description: Attempts to parse the &substring_t @s as a decimal integer. On
148 * success, sets @result to the integer represented by the string and returns 0.
149 * Returns either -ENOMEM or -EINVAL on failure.
