Subject: interconnect: Do not create empty devres on missing interconnects
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7562778563ada536bf52123ff06aa749cba2d1b9;p=thirdparty%2Flinux.git

interconnect: Do not create empty devres on missing interconnects

of_icc_get() returns NULL on valid case - no interconnects - but no
need to create devres for that, because it just wastes memory without
any use/benefits.
