drivers/staging/speakup/devsynth.c: fix "buffer size is not provably correct" error

2011-08-02T23:09:46+00:00

x86_64 allmodconfig:

In file included from arch/x86/include/asm/uaccess.h:572,
                 from include/linux/uaccess.h:5,

arch/x86/include/asm/uaccess_64.h:64: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size is not provably correct

I'm not sure what was unprovable about it, but size_t is the correct type
anyway.

Also replace needless min_t() with min()
