2017-09-30Input: melfas_mip4 - use managed devm_device_add_groupAndi Shyti1-16/+1
Commit 57b8ff070f98 ("driver core: add devm_device_add_group() and friends") has added the managed version for creating sysfs group files. Use devm_device_add_group instead of sysfs_create_group and remove the action that cleans the sysfs file when exiting the driver.
