Subject: drivers/staging/speakup/devsynth.c: fix "buffer size is not provably correct" error
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>

In file included from arch/x86/include/asm/uaccess.h:572,
from include/linux/uaccess.h:5,
from drivers/staging/speakup/devsynth.c:4:
In function 'copy_from_user',
inlined from 'speakup_file_write' at drivers/staging/speakup/devsynth.c:28:
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()
