general visitor application-surname misspelled

[em25]

I am planning to invite my mother to the UK. She will applying from India.

Issue is that her surname is misspelled. An alphabet is wrongly typed and all her supporting documents(bank statements, FDs etc) are same as in her passport.

The only discrepancy is between the surnames in mine and my mother's passport

Not sure how to deal with it. Any suggestions are highly appreciated.
