With well over 200+ users of this api, there are a mere 12 users that
actually checked the return value of this function. And all of them
really didn't do anything with that information as the system or module
was shutting down no matter what.So stop pretending like it matters, and just return void from
misc_deregister(). If something goes wrong in the call, you will get a
WARNING splat in the syslog so you know how to fix up your driver.
Other than that, there's nothing that can go wrong.Cc: Alasdair Kergon

The header socklnd.h includes irq.h which is not need
and doesn't exist in the OpenSFS lustre branch. Having
irq.h in socklnd.h does break the build on the m68k
platform. So we can safely remove it.Signed-off-by: James Simmons

strncpy_from_user could return negative values on error,
so need to take those into account.
Since ll_getname is used to get a single component name from userspace
to transfer to server as-is, there's no need to allocate 4k buffer
as done by __getname. Allocate NAME_MAX+1 buffer instead to ensure
we have enough for a null terminated max valid length buffer.This was discovered by Al Viro in https://lkml.org/lkml/2015/4/11/243
