applying patches to modules

[Uncle Fester]

I have to apply a patch to a module (therm_adt746.ko) and... it's my 
first attempt. I've read a lot and now I'm quite confused.
The right way should be:

1. # rm modulename.ko
2. # cp moduledir/ source.c patch.c
3. # patch p1 < patch.c source.c
4. # make
5. # modprobe modulename

Is it correct?
Thanks,
