X-Git-Tag: v3.18-rc1~130^2~824
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0a89e7147229d183f9e5566fc774d8e0dfeff627;p=karo-tx-linux.git

staging: comedi: amplc_pci230: absorb pci230_alloc_private()

`pci230_alloc_private()` is now only called from `pci230_auto_attach()`
to allocate private device storage and initialize various spin-lock
members therein.  Absorb the body of `pci230_alloc_private()` into
`pci230_auto_attach()` itself.
