From 2d98bb22c33b033182edd3a3c6b4c4e1d091db4d Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 4 Jun 2010 12:39:51 +0200 Subject: [PATCH] Staging: rc2860: return -EFAULT on copy_to_user errors copy_to_user() returns the number of bytes remaining but we want to return a negative error code. This is in the ioctl handler and the error code gets passed to userspace.
