Subject: net: ixp4xx_hss: drop kfree for memory allocated with devm_kzalloc
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=196073f9c44be0b4758ead11e51bc2875f98df29;p=uclinux-h8%2Flinux.git

net: ixp4xx_hss: drop kfree for memory allocated with devm_kzalloc

It's not necessary to free memory allocated with devm_kzalloc
and using kfree leads to a double free.
