Subject: sh: Remove sh_pcic_io_xxx function from Solution Engine IO code
X-Git-Tag: v2.6.27-rc1~29^2~44
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fafb7a97de73a917a875048801bd81cf64f79e4a;p=linux-2.6

sh: Remove sh_pcic_io_xxx function from Solution Engine IO code

sh_pcic_io_xxx function are very old.
In linux-2.4, mrshpc_ss socket driver used this function.
But there is not this driver to the present kernel.
I deleted these cords and checked operation.
