The error handling is mixed up. mux_chip_alloc() doesn't return an error
pointer (just NULL on failure), so check for NULL instead of using IS_ERR.
devm_mux_chip_alloc is documented to return NULL on failure, so fix that
as well.
All users of devm_mux_chip_alloc() are coded according to documentation.
Fixes: d47598cc669b ("mux: minimal mux subsystem and gpio-based mux controller")
