Subject: ser_gigaset: remove unnecessary kfree() calls from release method
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8aeb3c3d655e22d3aa5ba49f313157bd27354bb4;p=openwrt%2Fstaging%2Fblogic.git

ser_gigaset: remove unnecessary kfree() calls from release method

device->platform_data and platform_device->resource are never used
and remain NULL through their entire life. Drops the kfree() calls
for them from the device release method.
