Subject: Update ibm_newemac to use dcr_host_t.base
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=792036952123a0670c7dd6960ca5458cdfd5e4fd;p=linux-beck.git

Update ibm_newemac to use dcr_host_t.base

Now that dcr_host_t contains the base address, we can use that in the
ibm_newemac code, rather than storing it separately.
