usb: Fix warnings in chaoskey driver
> drivers/usb/misc/chaoskey.c: In function 'chaoskey_read':
> >> drivers/usb/misc/chaoskey.c:412:3: error: implicit declaration of function 'copy_to_user'
> >> [-Werror=implicit-function-declaration]
> remain = copy_to_user(buffer, dev->buf + dev->used, this_time);
I was unable to reproduce this locally, but added an explicit
#include <linux/uaccess.h>
which should ensure the definition on all architectures.
> sparse warnings: (new ones prefixed by >>)
>
> >> drivers/usb/misc/chaoskey.c:117:30: sparse: incorrect type in assignment (different base types)
> drivers/usb/misc/chaoskey.c:117:30: expected int [signed] size
> drivers/usb/misc/chaoskey.c:117:30: got restricted __le16 [usertype] wMaxPacketSize
Switched the code to using the USB descriptor accessor functions.
