Subject: cifs: replace code with free_rsp_buf()
X-Git-Tag: v3.17-rc1~59^2~34
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=6d81ed1ec22dbe96b85a5eb6422b2ab0556f7cbc;p=cascardo%2Flinux.git

cifs: replace code with free_rsp_buf()

The functionality provided by free_rsp_buf() is duplicated in a number
of places. Replace these instances with a call to free_rsp_buf().
