Subject: net: wl12xx: care for optional operations
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=77d7d7a36d270fee4591c1c99c83c2da1f399d44;p=deliverable%2Flinux.git

net: wl12xx: care for optional operations

->init and ->reset are optional - at least
sdio.c doesn't implement them - so allow those
pointers to be NULL.
