Subject: Staging: ipack: fix wrong return value.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=58b2c0ca0bd16ddefd1d981fe8748ca8083294c6;p=linux-beck.git

Staging: ipack: fix wrong return value.

In case it is not possible to remap the memory, it returns 0 and
the driver thinks that everything went fine.
