Zhen Lei bd95a3e159 visorbus: fix error return code in visorchipset_init() ... [ Upstream commit ce52ec5beecc1079c251f60e3973b3758f60eb59 ] 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.")
