Subject: mtd: brcmnand: drop brcmnand_host::of_node field
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d121b66d25adfa8b631dc59511ebc1d600ad5111;p=deliverable%2Flinux.git

mtd: brcmnand: drop brcmnand_host::of_node field

We don't actually need to stash a copy of this device_node indefinitely;
we only need it in brcmnand_init_cs().
