Subject: [S390] dasd: Use const in busid functions.
X-Git-Tag: v2.6.26-rc3~31^2~5
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=69f90f6a5650a74dd8f428e8d2f05859d58da3d7;p=linux-2.6-omap-h63xx.git

[S390] dasd: Use const in busid functions.

We should use 'const char *' in the busid functions since the
strings are not modified anyway.
