From: Roberto Sassu <roberto.sassu@huawei.com>

Add the description for missing parameters of evm_inode_setattr() to
avoid the warning arising with W=n compile option.

Fixes: 817b54aa45db ("evm: add evm_inode_setattr to prevent updating an invalid security.evm")
Fixes: c1632a0f1120 ("fs: port ->setattr() to pass mnt_idmap")

Among the previous patches I think there were 2 fixes like this one you could possibly also split off.
