report: scripts: checkpatch: Spell Checker Does Not Run with '-f'

[Federico Vaga <federico.vaga@cern.ch>]

Hello,

Recently I have produce a couple of patches but I get different warnings if I 
run checkpatch on the file (-f) or if I run it of a patch file. In particular, 
the problem I found is with the spell checker which seems to run only when the 
option '-f' is not used. I am wandering if there are other similar cases.

I do not know Perl, so I cannot investigate more, but I have a practical 
example. I have this simple patch applied on my tree that introduces a spell 
error:
