Subject: i40iw: Redefine i40iw_mmiowb() to do nothing
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b8546d7e23872c77d0ef6a4c311ac7037380c24;p=openwrt%2Fstaging%2Fblogic.git

i40iw: Redefine i40iw_mmiowb() to do nothing

mmiowb() is now implicit in spin_unlock(), so there's no reason to call
it from driver code. Redefine i40iw_mmiowb() to do nothing instead.
