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.
