From 8b86ed078a65433a60ff59091a136d23724bd6d3 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Thu, 26 Mar 2015 16:49:38 -0700 Subject: 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 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.
