This patch fixes these warnings:
fs/partitions/check.c: In function 'add_partition':
fs/partitions/check.c:391: warning: ignoring return value of 'kobject_add',
declared with attribute warn_unused_result
fs/partitions/check.c:394: warning: ignoring return value of
'sysfs_create_link', declared with attribute warn_unused_result
fs/partitions/check.c:401: warning: ignoring return value of
'sysfs_create_file', declared with attribute warn_unused_result
Got it right this time. Thanks Cornelia for help.
