f7b5964d4d fjes: Delete an unnecessary check before the function call "vfree"
The vfree() function performs also input parameter validation.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

47ea032533 drivers/net: get rid of unnecessary initializations in .get_drvinfo()
Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len,
eedump_len & regdump_len fields in their .get_drvinfo() ethtool op.
It's not necessary as these fields is filled in ethtool_get_drvinfo().

v2: removed unused variable
v3: removed another unused variable

This patch adds the basic code of FUJITSU Extended Socket
Network Device driver.

and retrieves ACPI resource information. Then creates
platform_device.
