This patch allows file2alias to generate the proper module headers to
support serdev modalias drivers.
Eg:
root@qt5022:~# modinfo serdev:ttydev | grep alias
alias: serdev:ttydev_serdev
alias: serdev:ttydev
root@qt5022:~#
cat /lib/modules/4.16.0-qtec-standard/modules.alias | grep serdev
alias serdev:ttydev_serdev serdev_ttydev
alias serdev:ttydev serdev_ttydev
