Subject: [SCSI] nsp_cs: fix buf overflow
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=edced191e4512b7795380563634f4d44b21c684a;p=openwrt%2Fstaging%2Fblogic.git

[SCSI] nsp_cs: fix buf overflow

In nsp_cs_config there is a wrong struct nsp_cs_configdata allocation.
It allocates only sizeof(pointer to nsp_cs_configdata) for a whole
structure. Add a dereference to the sizeof to allocate
sizeof(nsp_cs_configdata).
