Subject: Linux 4.2 compat: misc_deregister()
X-Git-Tag: zfs-0.8.0-rc1~152^2~155
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4fa4cab972899ecf6266c23986159a109dbcac5b;p=zfs

Linux 4.2 compat: misc_deregister()

The misc_deregister() function was changed to a void return type.
Rather than add compatibility code to detect this change simply
ignore the return code on all kernels.  It was only used to log
an informational error message of no real value.
