Dunno why this indentation, but if you need to send a new version, consider

static int st_lsm6dsx_push_tagged_data(struct st_lsm6dsx_hw *hw, u8 tag,
				       __le16 *data, s64 ts)

OR

static int
st_lsm6dsx_push_tagged_data(struct st_lsm6dsx_hw *hw, u8 tag, __le16 *data, s64 ts)

(yes, the second one goes to 83 characters).
