Zhen Lei ce52ec5bee visorbus: fix error return code in visorchipset_init()
Commit 1366a3db3d ("staging: unisys: visorbus: visorchipset_init clean
up gotos") assigns the initial value -ENODEV to the local variable 'err',
and the first several error branches will return this value after "goto
error". But commit f1f537c2e7 ("staging: unisys: visorbus: Consolidate
controlvm channel creation.") overwrites 'err' in the middle of the way.
As a result, some error branches do not successfully return the initial
value -ENODEV of 'err', but return 0.

In addition, when kzalloc() fails, -ENOMEM should be returned instead of
-ENODEV.

Fixes: f1f537c2e7 ("staging: unisys: visorbus: Consolidate controlvm channel creation.")
