Subject: Staging: solo6x10: return -EFAULT on copy_to_user errors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6a4ca0399255260bb04fa4e718625ede0c745e59;p=mv-sheeva.git

Staging: solo6x10: return -EFAULT on copy_to_user errors

copy_to_user() returns the number of bytes remaining to be copied, but
we want to return a negative error code here.
